Yikes! I think you have a good set of answers there.
Why don't you try the HIFamily Suites? I know they would cost you more than the AS but I believe they serve breakfast and kids eat free at other meals?
HIFS
My other suggestions would be one of the Marriott Properties in Little Lake Bryan. They have 3 Properties. I checked for 12/11 to 12/17 or something like that and found the following rates.
Fairfield Inn - Double Double - 56 to 75 (Cont. Brkfst )
Springhill Suites - 82 to 109 (Cont. Brkfst) By the way - this is my new favorite hotel. Fairfield has moved to 2nd place - we loved the one in Nashville. Ours had 2 TV's - don't know if they all do - but they have a fridge/micro etc.
Courtyard - Double Queen - 74 to 109 Suite 119 to 129 (no breakfast)
These are all newer properties within the last few years - I think they opened in winter 00-01.
I didn't check
AAA or Gov't rates but the lowest end on the above rates are for advance purchase then slightly higher for the other rates but not above highest I listed.
Just go to
www.marriott.com and put in Lake Buena Vista - they are the 3 properties at 8623 Vineland Ave.
Don't mean to sound like a Marriott salesperson, but I did check into these very heavily - waited for them to open when we went in '00 but they weren't ready - then checked again when we were planning on going to a conference in Orlando that fell through.
