*******************
The only thing I can advise is if you really want a particular view, you really do have to jump on the rates right away!
This year the AP rates came out starting for 4/23, so if you had gone this year on 4/21-4/28 your 4/21 and 4/22 dates would not have had an AP rate, and you would have had to split your ressie to be able to get the AP rates that started on the 4/23 date.....you would have had to book 4/21 and 4/22 either at rack rate, with
AAA (if you're a member) or switched resorts to save $$$ for those 2 dates, then switched over to AP rates res for 4/23-4/28 - IF they were available.
Hard telling though what dates they will use next year for AP dates!
