The thing that has always puzzled me about parking up front at WDW is that you end up walking MORE if you do that. If you park just wherever they put you, the determinate of how far you will walk is how far down the row from the Tram you are placed. Once you get to the Tram, then you have a ride to as close to the front door as you
can ride.
One of our regular party has a handicapped pass and she always wants to use it to park up front, so we do.

Most of the time, however, we end up walking FURTHER because the tram doesn't pick you up from the HC lot. It's a long walk from the HC lot to the front gate! Further in every case than riding the Tram.
