Actually, Magical Express is run by Mears, they just make it a little more "magical" for Disney. It is one of the benefits to onsite guests. I've not personally used it, but I know some people that did, and I've also read some stories online. Some people have had great experiences, but some have had problems. One situation was a family that was in Disney for a wedding, used ME and had all their wedding clothes in the suitcase (not really sure why) but the luggage was lost along with the wedding dress, tuxs, etc. I read all the time where people's luggage is lost, or it doesn't arrive for a few days. Several times when I was on the Disney Cruise I have had other peoples luggage delivered to my room. The ship is much smaller than Disney World and has fewer rooms, so if they have a hard time getting luggage to the right places on the ship, think of all the problems when you consider all the rooms at Disney. Most of the luggage is eventually found, as long as it isn't delivered to the wrong room and the person keeps it. Just be sure if you plan to use it that you bring an overnight bag with some clothes and any essentials that you may need, i.e. medicines, diapers, etc. I believe they still allow people to carry their own luggage, but it can be a bit of a hassel getting on and off the bus. Personally, I always get a private transfer so that I can get to my resort fast. That is another thing you have to consider, with Magical Express it can take quite a bit more time to get to your resort. Not so bad, except in a few situations. For example, if you want to get the parks fast, have something reserved that you need to get to, or have a flight very early in the morning. Factoring in the the two hours or so you should arrive early at the airport, plus the additional time you need to take on Magical Express, you may need to leave at 4 in the morning to get to a 7 am flight. If you want to save the money, it is worth giving it a try. Some people love it, some people have problems. I think I would rather rent a car so you can get around Orlando, if you don't mind the driving. Have a great time in Disney!
