Our Disney trip was full of glitches - from not having charging privileges at CBR to not being able to access our dining plan at BC CL! We had a triple split-stay (AofA, CBR, then BC CL) and I know that contributed to the problems. We tried to avoid any issues by physically checking in at CBR so we could be sure everything was set up correctly and we were properly checked OUT of AofA and checked IN to CBR. Unfortunately, we couldn't charge snacks to our room a couple hours later at Starring Rolls and then, even after getting help from our TA and me making a trip to guest services at Hollywood Studios, we STILL had problems when we went to charge the gratuity at Sci-Fi. It was SO irritating. Sci-Fi put in a call to CBR and got our charging privileges going at that point so from then on we were fine, but GRRR...
Then, when we were ready to check in at BC, our reservation was completely messed up. At first they told me they'd have to "rebuild" it, later they said they were able to fix it instead. Unfortunately, the problems didn't end there. We had two rooms (family of 6) but somehow the dining credits weren't pooled and I only had access to half the credits. My husband seemed to have access to all the credits. However, NEITHER of us had access to one set of snack credits! What a nightmare! They did comp us some money (one amount on the initial check-in and another amount the day we checked out because of all the trouble we continued to have), but wow! I hope to avoid split stays in the future. It was WAY harder than people made it out to be, at least for us. NOT worth it.
