Palo books more like a standard restaurant - 15 minute blocks vice two "seatings". If you have the early seating in the other restaurants, you should be able to eat with your son, eat at Palo, and make the 8:30 show, but only if he's an efficient eater and if you're quick,too! We enjoyed spending a bit more time at Palo. Have you considered a room service dinner for your son that night while you get ready for dinner at Palo?
