You should be able to book now with the Open Table app. We just returned from a 4 night stay. Didn't need to make any reservations. We ate at Hard Rock Cafe, the Palm, Mythos, The Leaky Cauldron and Margaritaville. The only wait was a 15 minute wait at Mythos. It may be a little busier in October with fall breaks for some schools, but you don't have to plan out and reserve your table service restaurants like at Disney.
