When we moved from BCV to BWV in June, we were told at BCV that we had to be there when they came to pick up our bags to go to storage. At BWV when we checked in we were told that we had to be in the room for the bell service to deliver. Since the room was not ready at that time, that meant we had to call bell services when we finally got into the room. Therefore, it seemed as though they structured it so they could get a tip at both ends. I didn't mind this since I would have tipped at both ends anyway.
On the other hand, there were items that we wanted refrigerated during the wait at both ends. When the items were brought to our room at BWV it was obvious that they had been unrefrigerated for some time. When I brought this to the attention of the bellman at BWV he said the instructions may not have been conveyed during the transfer. Moral: If you're transferring items that need to be refrigerted mark that clearly on the containers. I had asked the bellman on the BCV end if we should do that and said it wasn't necessary.
The good news is that the bellman said if anything was spoiled because it wasn't refrigerated to let the bell manager know and they would pay to have it replaced. Other than that the transfer went smoothly.
