Every time we do Disney, we spend our first night at Disney Quest - depending which night or day you are doing, I'd plan for three hours Max. Friday nights are crowded and I suspect Sat. afternoons as well - but other than that, we've always been in and out in about 3 hours. If it's not too crowded, you'll have a blast! Don't miss the design your own roller-coaster - if you're a chicken for the real ones, like me, you'll love riding this kind! Have fun, Melissa
