Hope you see this before you go, since it's late here (ds is teething!). Very proud of you to be brave enough to go across country traveling solo. Especially since you've never been there before! You sound like you've done all of your research and are very prepared. Ask questions from staff (airlines, ground transport, resort cm's) if you are ever lost or need any advice. I've driven many times by myself in that area, and been lost many times. Once I got situated I was fine. It's weird being from California and sometimes having to go West but that's an odd concept when you know Disney world is East!! Once I was on property though, everything fell into place and life was gooood! Since the flight is sooo long and the 3 hr time change is on the first day, and getting to the resort, checking in, etc, be prepared to not do too much the 1st day. I'm always amazed at people from the East Coast being able to just go to the parks on the same day they left their house! WDW is so large, you are going to have culture shock (in a good way)! I will never forget how I felt the first time there, how after each day I would be so fulfilled from that day's experiences and then realize the next day was a whole different park!!! Amazing! Enjoy the world, there's nothing like it!
