We only visit once a year, and my 4 yr olds bday is what we're coming in for this year. I am inviting my family and our friends since we are only going to be tehre for a weekend trip so we can see everyone and they can meet the new baby we had also. this is about 42 adults and 10 kids and some know each other, some dont. some are family some are just friends. the party will be outside in a private park with tables, chairs, walking paths whole things is about an acre big). i have games for the kids to play but what do i do with my adult guest to keep them occupied? i dont want them just sitting around in chairs bored looking even though they are enjoying seeing us, i want them to have a good time. any ideas?
