I was also checking for this week and was surprised to see no availability. I called and the CM explained that with Easter being so late in 2014 it is messing up some school's winter breaks. So the schools are scheduling winter breaks for earlier in the year than usual??? He said that the lack of availability is likely due to all the rooms being taken with "room only" reservations. This all seems a little strange and unlikely to me?
I am going to keep checking! If anyone hears anything different or finds some availability for the early part of 2014 please post back!
