Where? In a park with BBQs
Time/Duration? 2 hours (officially)
How many guests? my Mothers Group and some family and close friends...mebbe 25ish...
Did you combine family with friends or do seperate things? combined...made it easier for us as family lives out of town
What worked? the open space
What didn't work? non children friends found the event fairly overwhelming and couldnt really mingle with the main group.

My tips: the simpler the better! simple party foods that way people can wander around the food table and you aren't too busy in the kitchen putting together finicky foods.

A big mat with simple toys for the bubbas to play with. gives a centre focus for the kids to play.

hope you have a gorgeous day celebrating this special day!
