We are DVC BLT owners and had to change our reservation back in January. we were supposed to be there this week!!! but due to schedule conflicts with other members of our party, we had to push it back to Dec. We have been at this time back in 2006 and thought the crowds to be manageable, but crowded nonetheless. still better than going in June, July or August. we were booked for a 2br MK view at BLT, but when we had to change it, we had to split our week into 1/2 of Lake view and then check out and then check back in to our MK view. We look at it this way, we get the pleasure of getting both views and ending it with the MK view. Yes we have to go to the trouble of checking out and checking back in, but we have nothing scheduled for that day anyway..it is our "free day" to do whatever the kids want to do.
however, we are on the "wait list" for the 2 br MK View for our entire duration. We just are planning on being able to get it. But, we'll see!!!!!
