We're planning to go to WDW next year in late January/early February with some friends (my best mom friend and I have daughters that are besties and are the same age!). Each family will have their own room and we want to stay at BLT to be able to take advantage of the monorail and so we can walk to MK. When would be the best time to book, IYO, if we want to book via a site like Davids?
