It's going to be a reception (not the actual wedding, which is happening with only a few guests in a tropical paradise). We are on a tight budget, having it at his parents backyard. I'm scared it's going to rain, or be cold, but tents's are super expensive. The invites are already sent, so I can't change the venue to somewhere inside (plus as I mentioned, tight on money). We are having a taco truck do the food. I have family and friends coming from all over and I want it to be a good experience for them. I'm older now, and so are a lot of guests - I typically leave parties early, but I want this one to be one people want to stay for. What are some fun games or things we could do? Any suggestions would be greatly appreciated!
