I....won't be sleeping so much as taking a long nap. I get off at midnight before we leave, so I'll get home around 0100, take a long nap till around 0530, get up, eat, shower, shave, double check luggage and get out the door to make sure we're at Dulles at 0830.
Thankfully, we're not doing the parks on arrival day, so once we get checked in at Coronado, I'll take another nap before dinner at Rainforest Cafe
