On my last stay at AKV, I had our
ECV parked in our room, and Bell Services told me to park the ECV in the hallway. He even moved it for me to outside the room. Housekeeping told me the same thing when they came by and I parked in the room.
So, I think this 'violation' is not well known by the CM's - or even actively ignored since I had it parked in the room and was told multiple times to move it to the hallway. They said they prefer it that way since guests have trouble getting the ECV's through the door while holding it open (which was the problem they saw me struggling with).
So, if this is indeed against the rules, then someone needs to tell the CM's. There is no way I would know and certainly if I am encourages against it, I am going to listen to them.
