The cancellation window for a hotel reservation depends entirely on the specific "rate type" you selected at the time of booking. Most "Standard" or "Flexible" rates typically allow for a full refund if you cancel between 24 and 72 hours before your scheduled arrival day (often 4:00 PM local time on the day prior). However, "Non-Refundable" or "Advanced Purchase" rates, which are usually cheaper, offer no refund regardless of when you cancel. Some high-end resorts or boutique hotels may have stricter policies requiring 7 to 30 days' notice, especially during peak holiday seasons. In 2026, many major chains have introduced "semi-flexible" tiers that allow for a 50% refund or a credit for future use if canceled within a shorter window. It is crucial to read the fine print on your confirmation email, as "no-show" fees usually equal the cost of the first night's stay plus tax. If you booked through a third-party site like Expedia or Booking.com, you must also adhere to their specific platform cancellation terms in addition to the hotel's policy.
