I'm flying into Tampa for a few days before a stay at CSR & will have a rental car. I wanted to return the rental at MCO and take DME to the resort. How can I take the magical express if I don't have a flight number?
You don't have to have a flight number. As long as you have the resort reservation and DME reservation, you're good to go. they have absolutely no idea how you arrived at MCO...you could have arrived on a plane, a car, or by yak. Doesn't matter.
