I agree with the above. You have to be really sure about your plans if using Priceline. I tried using it for one night in late December but didn't have luck with my bid, so just went another route.
Have you looked at
www.mousesavers.com or
www.wdwig.com for some of the deals they have posted for off-site resorts?
I'd continue to look around a bit before making a decision, unless you are traveling in the next couple weeks.
