or start free with a Scout watch — 1 watch, email alerts.
With roughly thirty accommodations and overnight guests only — no day passes — weekends are reported to sell out months ahead, and advance reservations are described as essential.
Adults-only properties run on a fixed, small supply of rooms chasing weekend, holiday, and event demand. Once the calendar fills, the only rooms that come back are cancellations — and they return to the booking calendar with no announcement, at any hour, and are gone fast. Refreshing the booking page by hand is how most people miss them.

Castle Hot Springs is in our coverage queue: we don't scan it yet, and we won't pretend otherwise. Join the watch — we're building coverage venue by venue. The moment scanning is live here, a cancelled room that matches your dates triggers a text with a direct link to book it yourself, in your own account, at the normal price — we never book, hold, or resell rooms.
