We're practically neighbors!!!
Coach USA is a shuttle from Sanford Airport to WDW. Ted and I took it to WDW on our first trip. They are just okay.... but if that's your only option, it wasn't THAT bad!
We waited for almost two hours before Coach USA had enough people to put in a van. Luckily we found some nice tables and soaked up the Florida sun. They filled a bus full of people, including those who had bought tickets after us, but made us wait for a van. They driver was very unprofessional. He smoked and complained about his job the whole time, and how late he was going to be getting home. We were dropped off at CBR last, after just about EVERY downtown Disney hotel. Ted was barely out of the van, and the guy had his hand out DEMANDING a $5 tip!!!! Needless to say, we rented a car for the ride back.
I think it was about $28 (each way) each adult, but that was a couple of years ago, and I'm not 100% certain. The drive to WDW is easy if you decide to rent. If we can do it, anyone can! Cost of a rental car with a code could be as little as $25. We pick up at the airport, drop it off at Downtown Disney the next day, and pick up a car for the ride back to the airport the day we leave. It's about the same price as taking the shuttle, and if you have more than two adults, it may be cheaper to rent a car for two days.

Look under ground transportation.
If my opinion counts for anything, Pan Am is the WORST airline. I would suggest Manchester and save your sister the hassle of a subpar airline. Southwest and UsAir constantly have flights much cheaper than Pan Am. Southwest even has many non-stop flights to Orlando.
I hope this helps!
