Our trip plan and budgeting has worked out even better than I had hoped, so now we really wish that we were staying at WDW for 10 days in July instead of 9. Problem is , we already booked our round-trip air from Philly when the rates first dropped (yeh for southwest!) and of course the airlines charge that awful $100 per ticket (and there are 4 of us!) to change your flight date. Any ideas on how I can add another day to our stay without having to cough up the whole $400 change fee? I could handle paying half of that. Thanks for any ideas 

Hi Gail)
the only extra charge would be if the flights were more expensive, then you would pay the difference.
