The split stay not working thing happened to us as well last month. Everything worked great for the first two nights at Poly bungalows. Moved to BWV and got the "come to front desk" text. Took a very long time and two trips to front desk to get all 4 of our bands to work to open the door. Then upon moving to SS for last two nights, same text to visit the desk. After long time there, they ultimately had to give us cards for the door. Bands still worked fine for park and charging, but not to open room. After seeing a couple other posts on this thread, I'm thinking there must be band issues when split stays occur, although we had no such issues last year with split stay.
