Travelocity Airline Reservations Impropriety

We're taking the kids and their friends to Disney booking a flight to Orlando, FL, from NYC. We knew there was a stopover, but while checking in we found out that the plane stops at one airport and leaves from a different airport to continue on to Orlando. This means getting all the luggage off the plane, getting a shuttle on our own (for $21.00 per person) to the other airport, and checking in our baggage again. It's like reading the fine print on a contract to notice that there are two different airports since they both say Washington D.C. on the flight schedules. This is ridiculous! I spoke to a supervisor who was of no help. This will be the day from hell and we are actually paying more money using Travelocity. DON'T USE THIS COMPANY!!!!
