Hey this sounds very similar to our recent stay. We were there April 30 to May 18th and we had a host of similar problems throughout our stay too. No texts messages at any of the resorts we stayed at (AKV, BWV, VB, BLT). Our keys wouldn't work at BLT and had to be escorted to our room at least 4 times to get in. Had the
DDP for 1 night at AKV and after checkout we had no access to our remaining credits even though we should've been able to use them on checkout day. We had to pay with our cc and go to the front desk to get them to reverse the dining charges (note we are done using the DDP). The CMs (esp. at BLT) kept telling us that the NEW technology for the magic bands was causing the problems. They would not even give us our keys to our room even though our room was ready because the family before us had dining credits to use and in order to "cut" our new room keys, they would have to close their account. (I think that is what happened to our DDP problem when we left AKV and moved to BWV). We had a good time, but it certainly wasn't without a host of issues.
