Yep, that's cool. Are you riding with some Potters, or did they just give you the tip?
We've never done a Limo or Van, but talked to some folks last year with a large group who chartered a van and were very pleased.
We've taken the Disney bus from the airport and from Disney World. Probably the way to go if you've got one child, because they play cartoon shorts on the way.
Last time we stayed in Port Canaveral with a rental. Country Inn & Suites (or Hampton, can't remember) let's you leave your car there and has a shuttle pick up. The shuttle is around $10 a person.
This year we're staying a Radisson. We can leave the car there, too, but the shuttle is free. We're on the 11am arrival shuttle.
