About 3 years ago, we arrived at the Orlando airport on a Saturday afternoon, and needless to say, the line was about 200+ people deep...all for Disney's Magical Express. My husband is not the most patient person and was not going to stand in this long line. I asked a Disney Representative if we could catch a taxi to our resort and still have our bags go with Magical Express. She said, "...as long as your bags are tagged, they will make it, and if I were in your shoes, I would probaly do the same." Needless to say, we did, and our bags made it just fine. We have since used the Magical Express, and for whatever reason, we now arrive on Friday mornings and everything goes off without a hitch. So, if you do this, make sure your bags are tagged, and they will make it to your resort.
