I wouldn't take my loss on a hotel until I've seen it. Not everyone has the same opinions. Too many times you can read reviews (here and at Trip Advisor) where someone will HATE, HATE, HATE the Holiday Inn-- but they were expecting the Grand Floridian!!
Anyhow, I bid for a 3* for the middle of March-- we got the Sheraton Safari for $38 a night-- 2 rooms. This hotel was great!!! I would LOVE to get this again, and for the price too!!!
I, personally, love priceline. I get alittle leary when traveling w/ our son. I'm always afraid of the day we can only get 1 bed. I have used them elsewhere too. This year I have gotten: 3* Sheraton Safari in Orlando for $38/nt, I got Holiday Nikki Bird 2.5* for $27/nt, and I got the Grand Hyatt in NYC 4* for $151/nt.
Pretty much w/ a 3* in the WDW area you are pretty safe. Try to avoid going lower if you can!! Some of the 2.5* and less aren't the best-- I've learned to hard way. I got greedy-- wanted to save even more money-- I've learned my lesson-- only 3* or better.
