Vacation-rental guest-count changes: an amendment-control study
Methodology
- Scope and unit: Review one request to change the occupant count after booking confirmation. Freeze definitions, the observation cutoff, and the inclusion window before examining outcomes. Include only traceable property-level cases available to the operating team. Exclude demonstrations, duplicate alerts, sales inquiries, and records without a reservation or property consequence. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Evidence method: Public sources define boundaries for privacy, access, records, property safety, and communication. They do not test STRVirtualAssistant or prove this workflow effective. Local artifacts supply observations; reviewer classifications and recommendations are inferences and are labeled as such. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Collection: Capture original count, requested count, capacity record, listing version, platform amendment, fee state, sleeping plan, owner decision, guest acknowledgement, and access update. Retain originals in approved systems and store controlled references in the review table. Preserve source, timestamp, property-local conversion, observer, correction history, and authority. Code reported, observed, system-indicated, approved, conflicting, stale, and unknown separately. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Comparison: Compare cases changed only in a message thread with cases whose reservation, payment, access, and property records were reconciled. Publish absolute counts and denominators for included, excluded, incomplete, conflicting, corrected, escalated, prematurely closed, and unresolved records. Stratify by property, channel, occupancy state, and case type before combining any result. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Reliability: Two reviewers apply the frozen coding guide to an ordinary-and-exception sample. Log disagreements, adjudication, and rule changes; then recode a stable sample. Agreement shows coding consistency only and does not establish safety, correctness, consent, or service quality. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Sensitivity: Repeat the descriptive comparison without the largest property group, automation-originated cases, and records missing final acknowledgement. If the direction changes, disclose the dependency and narrow the conclusion rather than presenting one pooled percentage as robust. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Authority and safety: STRVirtualAssistant may retrieve approved records, build timelines, draft updates, schedule authorized work, and surface contradictions. It does not decide law, safety, technical cause, contract meaning, money remedies, or access outside a standing rule. Live hazards follow emergency procedures first. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Limitations: The study cannot interpret contracts or law, judge suitability for specific occupants, or decide whether an accommodation or exception is required. Selection bias favors better-documented cases. Tools, permissions, contracts, local rules, properties, and staffing vary. Findings apply only to included records and the stated cutoff; they are not causal evidence, an industry benchmark, legal advice, safety certification, or proof of performance. [Study unit: vacation-rental-guest-count-amendment-control-study]
- Reporting: Publish inclusion and exclusion counts, missing-data and unresolved counts, cutoff, coding version, and counterexamples. Readers must be able to distinguish source statements, property observations, participant reports, authorized decisions, and reviewer inference.

Findings
- Evidence reading: Short-Term Rentals resource center, ADA Guide for Places of Lodging, and Federal plain language guidelines support explicit information, responsibility, and safety boundaries, but none answers this question for a particular rental. Local artifacts must carry any property-level conclusion.

- Operational interpretation: keep the request, owner decision, commercial amendment, property plan, and access change separately verifiable. Preserve earlier values with correction time and owner so the sequence can be reconstructed. An unknown remains unknown until a named source resolves it; a final task label cannot erase a contradiction. [Sources: Broadband Speed Guide; Household Hazardous Waste; Incident Response Recommendations] [Study unit: vacation-rental-guest-count-amendment-control-study]
- Counterexample: A fully populated table can still support a poor decision, while an urgent case may proceed lawfully and safely with fewer fields. Keep only fields that can change routing, approval, communication, or verification, especially when personal or access data would widen exposure.

- Inference limit: Record completeness may correlate with closure because easier cases, experienced staff, responsive guests, or better tools affect both. That association would not show documentation caused the outcome. Name plausible alternatives and the additional artifact needed before strengthening a claim. [Sources: ADA Guide for Places of Lodging; Refrigeration and Food Safety] [Study unit: vacation-rental-guest-count-amendment-control-study]
- Conclusion: Report omissions, contradictions, corrections, escalations, and unresolved cases beside denominators. The evidence can support a reproducible coordination boundary, not a universal promise. Authorized people retain property, safety, access, financial, legal, and technical decisions.

Research standards
Every review freezes its observation window before findings are calculated. Reviewers retain a row-level evidence ledger with the original artifact reference, timestamp, responsible role, status at cutoff, correction history, denominator, exclusions, and unresolved cases. Ambiguous records are coded independently before reconciliation, and both readings remain visible until an accountable adjudicator applies a documented rule. Missing information is treated as unknown rather than silently classified as success or failure. Sensitivity checks remove major record classes in turn so a pattern that depends on one owner, channel, event type, or reporting cycle is disclosed instead of presented as stable. Elapsed time is not translated into labor, an association is not described as causation, and local observations are not converted into external benchmarks.
Interpretation begins with counterexamples and the cases still open at the cutoff. A formally complete record may lack usable evidence, while an authorized alternative path may achieve the intended outcome without matching the expected workflow. The review therefore states the strongest alternative explanation, identifies the additional artifact that could distinguish it from the preferred reading, and records what would reverse or retire the resulting operating rule. Comparisons use the same field definitions and equivalent work classes; a material change in coverage, tooling, policy, or sample composition creates a new baseline rather than a trend. Follow-up records name the decision taken, responsible owner, anticipated signal, review date, exception path, and evidence required before a stronger intervention can be justified.
Governance checks keep only information necessary for the research question. Sensitive content is replaced with a controlled reference whenever an authorized reviewer can reproduce the classification without holding a copy. Access boundaries, retention expectations, correction ownership, disputed-interpretation routes, duplicate handling, spanning-record rules, and cutoff treatment are documented before release. Absolute counts appear beside percentages, small samples avoid false precision, and every external statement links to a listed source without implying that the publication measured the local record set. The proposed action must be proportionate, reversible, and reviewable. If the available evidence cannot support it, the gap becomes an explicit evidence request rather than an assumption.
