Well, when is it in February? The first part of Feb. is value season the second part is Peak season.
I have read that some of the DTD hotels have their own transport, but I doubt they'd be cheaper than the All star hotels or even the moderates. Plus if they stay at WDW, they can do the dining plan and we thought that was a great value, especially for the kids -- unless you are planning on getting a hotel with a kitchen.
Do they tent-camp? They could do that at Ft Wilderness pretty cheaply AND be on the WDW bus & boat system.
