I have not but I just want to remind you of the check in with airtran coming back home.
When you get to your hotel and in your room you need to call 1-407-284-1231 to pay for your bag fee when you go home. But if you upgrade to first class (39.00) if you are a A+ member you will not have to pay for the bag fee.
Plus, 24 hours before you leave you will have to do the check in your self by calling AirTran, Disney will only check you in for reg.seats and tell you when you need to be ready to go back to the airport.
I hope this helps
