I can't decide whether to drive or fly to WDW in December. Normally, I drive, but this is my first trip solo with DD4. In the past, I've had my mom or sister with me. My main concern is keeping her entertained while I'm driving. It takes about 7 hours to drive. Flying may end up being more of a hassle though. It takes about an hour for me to get to the airport, I'd have to get there 2 hours early for security/check-in, fly for about 2 hours, and then take a taxi or shuttle to our resort. Cost isn't as much of an issue as convenience. What would you do? Does anyone out there have experience driving solo on a road trip with a 4 year old?
