I communte 14 miles a day one way to work, not even a bus comes to where I live and goes to where I work. It is all interstate driving, with the exception of a few miles of city streets. When I was in Europe 3 years ago the transportation system was extensive and I had many options to travel within a city and to another city on the public system (Italy and France). So, while I am grateful we don't pay that much (compared to England, etc...) I am also aware that we (Indianapolis) don't have the public transportion system you have either. I couldn't even take the train to Orlando if I wanted to. I would have to go to Chicago (about 150 miles north of me) just to get a train to go 1150 miles south (past Indianapolis, but no train stops here going south) to Orlando. When I went from Florence Italy to Rome I had the choice of 16 different departure times in one 24 hour period in which I traveled. I would LOVE to have that option but Americans are in love with their cars and we drive big cars, the bigger the better or so it seems. We have abandoned our rail system and have yet to develop a decent public transportation alternative.
To the OP, I am sorry your trip is out of the question this year. I had to cancel a trip to WDW last year (for health reasons) and I know how you feel.
