I'm going to be in WDW 3 times within 1 year (7 days each) and want to get info on a season's pass. I'll need one for me and my wife, and one each for a 4 and 5 year old. I live in PA. Do you have to be a FLA resident? Can these be bought anywhere or only thru Disney? Do any of the vacation clubs' discounts apply to season passes? Thanks in advance.
