When I was there May 13th-May 22nd, I spent two nights at POP, then transferred over to BWV for five nights, then back to POP for the last two nights. When I checked in about noon on the 13th my room was ready, so I carried my carry-on bag up to the room and then left for the parks, room key in hand. When I returned that night my DME luggage was waiting in the room for me.
When I checked back in seven days later around 8:30am my room was not ready, but they gave me my room key and a number to call later to get my room number. When I arrived back that night, my bags were again in my room waiting for me. They told me when I checked in that I had room charging priviledges if I wanted it, even though my room number was not officially assigned at that time. The same thing should apply for MYW dining priviledges.
