Prices drop closer to check-in — but not at the last minute
  • • 3+ months out: median $375/night
  • • 61–90 days: $336/night (10% cheaper)
  • • Consistent ~$39 savings per night
No last-minute discount — the opposite
  • • Prices bottom out 61–90 days before check-in
  • • Prices tick back up in the final week
  • • Last-minute booking ($436) is 30% more than optimal
Best time to book: 61–90 days
  • • Median price $336
  • • Cheaper than both far-out and last-minute booking

Book 61–90 days ahead for the best rate (~$336). Don't wait for last-minute deals — they don't exist at this hotel. And don't book too early (90+ days) either — you'd overpay by ~10%.
