We tried to book in on the day through the SL concierge desk, but there was no availability for either that day or the next. The lady on the desk advised us to call in at the restaurantto see if they had any cancellations, which I did, and we managed to get in the next day. It is very busy, but the character interaction was very good. Please read my trippie To Infinity & Beyond, as it contains a full report on all the characters that were there, and a bit of advise about the buffet, which is laid out in quite a strange way!!
