As of two weeks ago, the time of baggage drop off is three hours before your flight departure. So...here's the how to for you....
let's say your flight is at 11:00 am (and of course, it is a participating airline). If you are using DME, you will most likely get a pickup time of about 8:00ish, give or take 20 mins either way. As for checking your bags....I like to get rid of my bags as early as humanly possible. So, I would be at the RAC desk, in the lobby of the resort, by 6:30ish. There, you will be able to check in for everyone in your family....at least that is what I have heard. Your bags will be tagged with the appropriate airline tags, you will be issued your boarding passes for your group. I have yet to have any issues with sending my bags through them....worked like a charm every time.
Be sure to be at the DME bus stop 15 mins before your designated pickup time. That time is the 'departure' time, not the time you should show up!!!
Any other questions? Just ask.
