65 rules in this category, extracted from the Club Wyndham Members Directory and explained by ShareHacker Research.
Club Wyndham's booking-window system is four separate time buckets stacked on top of each other — each with its own eligibility rules, each opening at a specific date before check-in, and each favoring a different owner class. If you only know that "ARP is 13 months" and "booking opens at 10 months," you're missing the entire competitive structure. The four windows, reading from earliest to latest against check-in:
ARP (Advance Reservation Priority) opens 13 months before check-in. Only available at your home resort or, for certain contract types, at your home collection. This is where Presidential Reserve, deeded-week, and ownership-type-restricted inventory gets booked before the general Club Wyndham pool sees it. Rule `cwus_advance_reservation_priority_arp` covers the eligibility matrix in full.
RARP (Reciprocal ARP) opens 11 months out. This is a VIP Gold-and-above-only benefit — it grants ARP-like booking privileges at non-home resorts, one month after standard ARP. For VIP owners, this is the single most under-used benefit in their tier. See rule `cwus_reciprocal_advance_reservation_priority`.
Standard booking is the window most owners think of as "the booking window" — 10 months before check-in, open to everyone in the Club Wyndham pool. By the time standard booking opens, ARP and RARP have already siphoned off the Presidential suites, the Prime-season Deluxe rooms, and the holiday-week inventory. What's left is 60–80% of the available inventory, which is still plenty for flexible travelers.
Express Reservation (`cwus_express_reservation_window`) opens 3 months out. Minimum 2-night stay, borrowing points is unrestricted, and point rentals are uncapped. This is the "I forgot to plan" window — and it's where the VIP points-discount stacking lives, though the discount itself doesn't activate until the 60-day mark (`cwus_points_discount_window`).
The practical calendar we've drilled into the ShareHacker research database: if you're a standard owner targeting a Prime week at a high-demand resort, your realistic window to book is 10 months out, first thing in the morning, on the day standard booking opens. If you're Gold VIP or above, you push that to 11 months via RARP. If you own at the resort, you push it all the way to 13 months via ARP. And if your trip is inside 90 days, you're playing the Express-plus-points-discount timing game we break down on the individual resort pages.
Two things everyone misses: the borrowing-points rules shift per window (ARP lets you borrow up to 100,000 points; Express lets you borrow without cap), and the cancellation-penalty structure ALSO shifts per window — a 10-month ARP booking has different cancellation math than an Express booking. We link out to each rule below with its specific conditions and the directory page we pulled it from.
