I know it's a long time away yet, but we're going to DL from November 14-21 (me, DS14 & DS11). We're trying to keep costs low so we won't eat in the parks most nights. Do we need to make reservations for restaurants in Downtown Disney or along S Harbor Blvd? If so, can we book that day, or do we need to book further in advance? Whilst I know a couple of places we want to eat, I'd prefer to decide Where each day - but without having to queue for an hour!
