We just came back from a 12 night stay at BLT (6/29-7/11) with lots of segementing. This is the 3rd time we have segemented a stay, but this trip had lots more segementing because it was a long trip.
As long as you are prepared for frequent trips to the front desk for checking in and out, you will be okay.
We did 1 night no plan, 3 nights deluxe, 1 night no plan, 3 nights regular dining, 1 night deluxe, 1 night no plan, 1 night deluxe, 1 night no plan. We also liked the idea of deluxe every other night. It's cheaper than the regular meal plan everyday, plus you get appetizers.
We did have problems. On our second day, we got locked out of our room and we had to wait about a half hour while they cancelled and rebooked the room. We had this same problem with our trip in April. The manager says they have this problem frequently with segementing.
Also, housekeeping gets really screwed up. I basically had to call and get the services we were suppose to get. They never came when they were suppose to. On 3 separate occasions, they were knocking on my door telling me that we were checking out, when we weren't.
We like segementing because it works for our family, but it does take a toll on you. We had to go to the front desk a lot, some times twice a day because there were problems with the keys or the dining credits. I will wait and see what we do in October.
