The ceremony is at a hotel and then we are providing the transportion for our 70 guests to a restaurant 45 minutes away for our celebration dinner. Pictures after the ceremony are going to take about an hour (hopefully less- but I've been told to expect the hour). Only half will be needed for that formal/posed picture time. Since our dinner is at another location where parking is difficult- most will use the provided limo transportation and won't leave before us for a traditional reception cocktail hour. What should we do for our guests during that hour? Anything?
