I used the resort check in 2 weeks ago for my luggage. I was NOT using ME but they sasid it didn't matter, I could check my luggage in there, as long as it was one of the participating airlines. What a nice perk, because I had just spent 3 nights there and 14 nights on the Magic and a night in CA before that, so I had some heavy bags. It was a relief not to have to check them in at the airport, not to have to schlep them form
Avis to the ticket counter and then to xray. And I got my boarding passes from the desk also, so I only had to go through security and I was on my way.
