We stayed at BC for 4 nights and Contemporary for 3. It was not planned that we split our stay. We were not that impressed with the BC rooms. My 3 yo son was scared of the illuminations fireworks every night at 9:30pm. They are really really loud, even from the shower I could hear the banging!! The room was small, we had to leave our strollers by the door because there was no room in the room. Since after the 4th night, our plan was more towards the MK, we decided to change resorts. First, if anyone is planning to do this unexpectedly, the best thing is to call the resorts yourself. Don't have them or call the central booking number. I had the BC front desk call around the night before and she found a room at the poly (she talked to the front desk directly). She then told me that the poly cannot book a room for me that I had to call central reservations at 7am and do it myself. So, I did. But they told me they had nothing at any of the 3 MK resorts. So, I took matters into my own hands. GF had nothing, but contemporary did. And the room was awesome!! Way bigger than BC, walking distance to MK, on the monorail. Since our last few days were mainly MK, and the MVMCP, this worked great for us. The new rooms are great. But I have to say that BC lobby and pool were way better, more personality, I think. But the split stay turned out great for us. They transferred our luggage, no problems.
