Okay...here goes.
You should get your info packet, with one luggage tag pp and vouchers for each person, up to 4 weeks before departure. This packet will tell you pretty much everything you need to know. It will also have a map for you so that you easily find DME...although it isn't that hard to begin with.
You will put a luggage tag on your checked luggage. If you think you may need more than the one pp, call and ask for more. Say goodby to your bag(s) at your home airport. When you get to the main terminal you are on level 3. You need to go down to level 1..ground transportation. Head over to Side B...just look up as you enter the main terminal after the sercurity area, you'll see the big neon Side A and Side B signage.
Go down to level 1, and look for DME. It is all the way at the end of the area. You will checkin, either at the counter or at the start to the counter line...depends on the current situation there. Your vouchers will be scanned, you will be asked how many bags and about your return flight plans. Then, it's off to the bus lines. There is a line for each resort. Go to your resort line. When the appropriate bus comes along (every 15 mins or so) you will be directed to the right bus. There may be 2 or 3 other resorts included on that bus. When you get to your resort, hop off, get checked in. Your bags can be expected to arrive in your resort room up to 4 hrs after resort checkin.
Hope that helps some.
