Both reasons really
Value is a MAJOR player in it. PLus we like to go alot for weekends, etc. and normally when we go, we go to the parks, so we dont feel the need to sleep in a 400$ a night room, and then be gone from it all day.
at 49, or 59 a night, you cant beat the disney vibe ( although ASMo did botch our trip with them pretty bad, we doubt we'll go back to that one. We cant wait for Pop Century.
BUt We also like the hotels, they are all we need most of the time, and we feel staying there, leaves us all the exra money we need to go to places like Victoria and Alberts, CG, CRT, etc.. I'd rather stay at a cheaper hotel, and go all those great places..
Eventually, when we go just for the sake of being at disney, We'll stay at a moderate, Heck, that might be our goal, we've stayed at all 3 values, now we can move on to modersate, and keep climbing the chain!
