We purchased at Aulani last year and this will be our first trip there. I'm still learning the ins and outs of DVC so thanks for your patience Planning for 7 days (12/26/21 - 1/2/22) in a 2-bedroom Island view. I know that's a busy time of year...Should I attempt to walk the reservation or should I be fine to book at my 11-month window? Thanks so much!
