I'm 3.5-4 hours away and I used to do it pretty often and yes it is crazy to wake up at 4 or 5am do the drive to get to the parks at 8 or 9am,spend the day at the parks walking around all day and then drive back at 9-10pm to get home at 1 or 2 am.Many times we did the one day thing because of some group we wanted to see at the EPCOT concerts or a special event and we could only make it one day.When gas prices jumped to $4 a gallon we went from doing it pretty often to just every now and then.It is very tiring, you don't get tired of visiting Disney,but you do get tired of the drive.If I was two hours away I would be at the parks at least weekly,two hours each way in one day is nothing compared to 4 each way.I've realized I need to move closer to the parks,I put over 300,000 miles on my last car and my current one is at 95,000,all highway miles.
