Mostly, the bonus of having an AP is a year of admission for about the price of a 10day-Hopper-no expiration.
AP rates aren't guaranteed and sometimes they don't have AP rates available for all levels of resorts. The rates vary too.
These are just examples of the AP rates we've gotten :
BWI $218+tax (Value season) regular price $330
AKL $185+tax (Regular season) - the general public code was better, $149/night regular price $265
POP $79+tax (Regular Season) - again the GP code was a better deal, but didn't work for our dates. regular price $99
ASMU $59+tax (Value Season) regular price $82
WL $185+tax (Pre-Christmas season) regular price around $350
BC $279+tax (just before Christmas) regular price around $500
Personally I wouldn't buy an Annual Pass SOLELY because of room discounts. Lately the general public offers, although limited, have been just as good if not BETTER than the AP rates.
But if you're going to get an AP anyway, and if you're flexible about the resorts you want to stay at, then go for it. We sure are enjoying ours.
