I would book at least 2 hrs before you ressie. It takes about 45 mins but if they are running late and pictures and if they aren't seated at the same time once you factor all of this in the 2 hrs is the absolute minimum. It might not take this long but its better to be safe than sorry. HTH, if you have any more questions if you post them on the thread link in my sig they may be answered quicker also there are two or three fairy godmothers in training.
