Our ceremony is at 5 pm. It doesn't appear that it can be pushed back much later, although I am still looking into that option. It will be a bit on the longer side and there will be a receiving line, so I expect the whole thing to be done around 5:30. It is a 25 minute drive to the 6:30 reception.
What can we do to entertain guests for the half hour gap? I wouldn't be opposed to providing light appetizers at the ceremony venue, but I also don't want to end up needing to rush out after that. Would it be appropriate to just hang out in the park where the ceremony is and chat with guests?
