Methodology
How this score is computed
Methodology
How this score is computed
total = 0.25 × 88.5 (Guest Experience) + 0.25 × 80.8 (Group Readiness) + 0.20 × 80.6 (Setting) + 0.15 × 85.4 (Dining & Wellness) + 0.15 × 86.5 (Value) = 84.2
Value 86.5 = 0.5 × 78 (editorial base) + 0.5 × 95 (from $39/night median — Google Hotels, Aug 29, 2026)
Guest Experience 88.5 — consensus of Google (4.7★/1,118) and TripAdvisor (4.7★/5,069), each Bayesian-adjusted and review-weighted, then blended with the editorial base (base weight decays as pooled reviews rise), Aug 9, 2026
Five pillars, each scored 0–100, weighted per the published methodology. Each pillar is labeled Computed or Editorial above, per venue: Value and Guest Experience convert to a 50/50 blend of the editorial base and the computed input as live rate data and verified guest ratings land; Group Readiness is editorial, anchored to the property facts shown above; Setting and Dining & Wellness are editorial judgments against published criteria. Every change lands in the append-only readings ledger below, and venues may submit verified data for the next edition. No venue pays to be ranked.
