Wedding Day/recieption with our 8 month old

We are getting married in august and our daughter will be 8 months. We are trying to get a game plan together for her so we all can enjoy the moment as a family :) we have a family member caring for her during the day and taking her for the night but any recommendations for what we should bring or ideas for comfort for her to keep her happy? Anyone else have a young child to at the time of their wedding? Her bedtime makes me most nervous since she usually goes down between 7 and 8 our ceremony is at 6-6:30.
