ticketwm35,
I'd switch as well. From what I've read, you've stayed at the AS more than once, so try something new! Try out one of the delux hotels for a change. I've found it can be a mistake to try to "re-live" the same vacations you had in the past - that can be problematic, limiting and unfulfilling. (Not that you ARE trying to do that...

) Its just that there are so many awesome, wonderful experiences awaiting you at the World, it would be unfortunate to let habit keep you from them. Sorry to be so philosophic, we are talking hotel reservations after all.
The Poly has a great pool and beautiful surrounding gardens. Being able to pop onto the airconditioned comfort of the monorail can't be beat. Its a BIG plus. Try renting a watermouse or sailboat. Talk about cheap entertainment! You can do that at the GF, the Poly or the CR.
If you plan on spending a good deal of time at the resort, then you probably won't want length of stay passes to the parks, so that could save you some money.
A lot of people say that Storm along bay is very best hotel pool in WDW. Consider staying at the BC or YC - very convenient for Epcot and not very far from the MK. Will your stay in October be during the
Epcot International Food and Wine Festival? If so, you won't want to miss that... and the BC is the perfect place to enjoy it.
