No way!!! We usually get there at opening, enjoy ourselves through lunch and then head out somewhere between 1pm and 3pm. We go back to the resort to swim, nap, or check out boats or bikes.
Sometimes we go back in the evening, sometimes not. We usually catch dinner, go mini golfing, go to DTD, or just relax in the room. Since we starting going multiple times in a year and bought into DVC, we really don't feel any need to rush or kill ourselves. If we don't hit it this time, we'll hit it next time!
