Yes, she's correct. When using the 13-mos Reservation Window for Weeks, you must book two or more Weeks or lock-off components of two or more Weeks into consecutive/concurrent weeks on the calendar.
A few notes about Weeks reservations:
- Marriott is allowed to release only 50% or fewer of the available inventory at the 13-mos window, then at 12-mos all of the remaining inventory is released.
- 13-mos Weeks reservations cannot be processed immediately in the online system. You must call in and with high-demand inventory, you should be calling the minute the phone lines open at 9AM Eastern. There's a link in the Weeks online reservation process that allows you to send a request for 13-mos consecutive/concurrent reservations but those requests are not processed until after the phone lines clear on the Release Days. Do not trust that high-demand inventory will be available through this process!
- It is not required that the multiple Weeks/components you're booking must be at the same resort OR in the same season OR that consecutive calendar weeks reservations must all begin on the same day of the week. Using my ownership as an example, prior to the DC/Abound I routinely (more often than not) booked some combination of consecutive SurfWatch Gold, Barony Gold and SurfWatch Plat Weeks, in whichever combination was available over the Memorial Day or Labor Day holidays. Both of those resorts have Fri-Sat-Sun check-in days of the week and several of my consecutive reservations were deliberately booked with different check-in days so that in between I could work in an overnight or two at hotels in Savannah.
- The Marriott Weeks and Points inventory is released on different days, and, each system has its own online reservation process. If you're using Weeks to book, then you use the Weeks system and if you're using Points, including Points from enrolled/elected Weeks, you use the Points system. (I know, sounds simplistic, but people have been known to be confused by it.) The website's very slow this minute but you can check out the Helpful Tools section to determine the correct Release Date for your desired stay.
