Release days & booking windows.
Most sold-out bookings were first released on a schedule. Know the schedule and you can be ready the minute it opens. Then let Nabbi catch everything that comes back afterward.
Always double-check the official pageRelease rules change from season to season, and each campground, permit or museum sets its own. The patterns below are a starting point. The official booking page has the final word.
| What | First release | What comes back later |
|---|---|---|
| Recreation.gov campgrounds | Most use a rolling window, often up to six months ahead. Some release a block of dates on one set day. Many release in the morning, Eastern time. | Cancellations every day, with spikes before cancellation fees increase and in the final week. |
| Wilderness permits | Often an early lottery or a large release months ahead, with part of the quota held back. | Held-back quota released closer to the date (often days ahead), plus cancellations. |
| Timed entry (e.g. Rocky Mountain, Haleakalā sunrise) | A large share released weeks to months ahead during the reservation season. | A second batch is often released a day or two before, plus same-day returns. |
| Park lodges (Yellowstone, Grand Canyon, Glacier, Zion) | Often a year or more ahead. | Cancellations all season, especially before the lodge’s cancellation deadline. |
| Anne Frank House | Every Tuesday at 10:00 Amsterdam time, tickets for the date six weeks out. | Returns in between. Sold only on the official site. |
| Leonardo’s Last Supper | Quarterly blocks on the official site. | Extra tickets for the following week every Wednesday at 12:00 Milan time (single visitors, up to 5). |
| Global Entry, NEXUS & SENTRI | No release day. Centers add appointments on a rolling basis. | Reschedules and cancellations every day. |
| New iPhones | Pre-orders open on Apple’s announced date. Pickup stock arrives on launch day. | Fresh pickup stock through launch week, often early in the day. |
Your release-day checklist
- Convert the time. 10:00 in Amsterdam is 4:00 a.m. in New York and 1:00 a.m. in Los Angeles.
- Make an account the day before. Verify your email and add your details and payment method.
- Pick a first choice and two backups. Know exactly which dates, sites or time slots you’ll take.
- Be on the page five minutes early. Refresh right at the release time. Don’t open a dozen tabs, which some sites treat as bots.
- Missed it? Start an alert. That’s exactly when Nabbi becomes useful.
Let us remind you
For attractions with a weekly release, like the Anne Frank House and the Last Supper, Nabbi sends a reminder before tickets drop if you’re watching that date. You’ll also see upcoming releases marked Release on the “Just opened” board on the home page.
For everything else, an alert is the best reminder: it keeps watching after release day, when most of the second chances happen.

That’s when the second chances start. Set an alert and we’ll watch for returns.
