Well, I ended up with the most expensive option of all: Valet parking at Yacht Club. We were going to take the hotel bus to DHS and walk from there, but the bus never showed up. When I had 55 mins left before the ADR, we hopped in the car and headed for the Yacht Club. The traffic was a NIGHTMARE- and I learned to drive in Boston, am not phased by San Francisco or NYC traffic. Once I got to the YC I was told 2 hours free parking or $33 for valet, good all day at any WDW valet station. Well, I decided for the $8 difference between a theme park lot and valet, it was worth it to NOT have to go back out into the stupidity that was the highways around WDW on the morning of Christmas Eve. Other than the parking snafu and the drizzly weather, it was an amazing day!
