You don’t actually need to have a magic band to get past the gate at the Tower if you’re driving. There’s a call button on the box where you can speak to security. If you drive to the GCH entrance and tell them you’re checking into the Tower they will just send you over there anyway and wave you through, that’s what happened to me the other week when I was checking in. But you can still use the call button at the tower gate if you don’t go to GCH first if you need to be dropped off at the tower as a guest there, I took a few regular Lyfts (so not Minnie Vans) and had no problems with it.
Bell Services at the tower is just outside the main entrance to it, where you pull up to the doors, and if you drop luggage there it will actually be stored at the tower. They have separate ones for tower and the main Poly. But from experience when I was going home the other week, sometimes there is a bit of confusion trying to pick up bags from one that you dropped off at the other. There’s a lot of new CMs that just started at Poly. I dropped my bags off at the tower Bell Services that morning before hitting the parks and ended my day at MK, so I came back thru the GCH and was getting a rideshare to the airport from there. Went to GCH bell services and there was a little back and forth as they figured it out and had to get a senior CM to help out. It wasn’t a huge deal but something to bear in mind.
