If you are leaving tomorrow and just booked last week, you won't be getting your DME info packet. I am assuming that you booked your DME ride though. You have to have advance reservations in order to ride the bus.
You have a few options as to what to do with your bags. You can go directly to the DME checkin counter and give them a description of your checked bags, the number of bags and the claim receipts for them. They will send someone to get the bags and deliver them to the resort for you. Or, you can go to baggage claim yourself and get them. Then you can bring them with you to the DME checkin area and they will be put underneath the bus you are riding on.
So....when you get off the tram, from the gate area to the main terminal, you will want to look for the Side B sign, up above you. The airport is divided into Side A and Side B areas. Some airlines arrive and depart on each side. You will arrive on level 3. Head to Side B and go down to level 1..this is all ground transportation. This is where you will find the DME checkin area. Get in the line, they will check you in. You will be given a voucher in order to get on the bus. You will then be directed to the appropriate resort bus line.
If you choose to get your own bags, you will go down to level 2 before heading all the way down to level 1. Baggage claim is located on level 2. When you get your bags, you can then go down to level 1 and DME.
