To me, I would not chance this, but I would like to point out that my DH and I were once 45 minutes late for a reservation at Liberty Tree Tavern, and they welcomed us in. (We had to wait about a half hour, though, once we arrived.) I don't think that is a typical thing, but I just wanted to mention it. That night, almost everything that could have gone wrong did. We were already running late and then waited over a half hour for a bus from POR. We barely got on the first bus to MK in over half an hour, thanks to the sympathy of people who had been waiting far longer than us (they were so kind to let us and another young couple who had reservations go first) and a bus driver who initially said the MK bus (which was a ME bus?!) was full. Then, when we arrived at MK, we had to fight our way through a parade crowd. I was freaking out, called the dining reservation line, etc. Let's just say I've learned my lesson since then... plan for transportation to take an hour!
