Well, I HIGHLY recommend Southern Elegance.
I didn't want to post because I don't want them to become too busy that I cannot book them,

but I owe it to them to mention them as they have been nothing but top notch in every way. I have used them 5 times in the past year rt from MCO/WDW resorts.
They are just fabulous. Nice, personable & professional drivers, gorgeous new cars filled with cool gadgets that they take the time to explain how to use, and most importantly they have been absolutely reliable and responsible.
They will bring a giant stuffed Mickey, Minnie, or Goofy to ride along with you. The limos we have been in have had several tvs (3 to 5 in one car) with Disney DVDs playing when you ride. Cold sodas for you. It is just a treat to be picked up at MCO by them! The drivers have always been on time & met us at MCO with our name on a sign and helped us (actually tried to do it themselves) get our luggage from the carousels. They are always very nice and repectful to my kids, also.
I feel great having found Southern Elegance for our WDW vacations. Now I wish I could find as wonderful a company up here in IL to get us to Midway or O'Hare.
Happy planning!
