Some folks think it's a huge problem, but it's never bothered me,and we've done it mnay times.
Basically, the day you are going to move, pack your stuff, call Bell Services, and tell them you are transferring to another hotel. They will get your bags there.Go and do your day, and when you are ready to go back to the hotel, go back to your new one, check in, and they should have your bags to your room within a few minutes. Like I said, we've done it very often and have never had a problem.
The only other suggestion I would make is to stay at the better hotel last. For example, if you want to stay at POR and the BC, stay at POR first, as it has less amenities. If you stay at the BC first, then POR will be a step down, and you'll be disappointed.
