Building A Wedding Seating Chart Outdoor Wedding Ceremony Question?

Outdoor Wedding Ceremony Question? - building a wedding seating chart

Hello! My friend and I have our wedding in a local park on 31 May. I thought I had almost all the details down until I thought about it - our ceremony is scheduled for 1:00 Clock. Like most people, some get well soon, 12.30. Since this is a small meeting and seats are only for those who have been deployed (grandparents, etc.) need, one has any input, where to start these people to the ceremony? I thought, I think creates a table outside with a few drinks, comments, etc. If you have, it would be appropriate? The reception will take place in buildings that rented the park, but you do not want to draw people there and put himself in there, so that the ceremony in the afternoon. Advice is appreciated!

Have a good weekend!
