Kim--Yep, we're on Song. All things being equal, it's the way to go out of this part of the world for school vacation weeks. I can book 331 days out, and they book one way. (We'll be doing 5 days in WDW, and then driving south to Bonita Springs--and flying home from there).
We stayed in the cabins in January of 2004 and REALLY LOVED them too. It will all depend if my folks decide to come up and join us. If they decide to, we'll do the cabin. If not, we'll probably do a CR tower room.
Also, this year, the season switched from Value to Regular (or Peak?) on the Wednesday before President's Day.
And for what it's worth--we spent Feb Vacation this year in Bonita, and had 9 days of PERFECT 85 degree weather, with no rain until the day we left.
