We are Platinum and did a B2B Oct/Nov 22, and the big doors were closed to all the hallways so that you couldn't even get to your room. I thought that since we were B2B we would be able to get to our room, but we couldn't. So I would say that no, you wouldn't be able to get to them early. I do remember before that we could drop off bags, but with them closing the hall entry doors, I guess you can't any more.
