After a LOT of thinking & trying to schedule & stuff we have decided to go to Orlando a few days after Christmas through a few days after NYD. We plan on booking 1 night at a Universal hotel so we can get the early entry & the unlimited express passes for the 2 days we plan to be there (rest of the time we will be at Disney & I'll be booking a condo or house). If I book during the summer should be be fine? I want to book early enough for a possible better deal.
