For mine we rented a shelter at one of the local parks and had HyVee cater?
Was relaxing, kids (and some that are "bigger kids" and Boxsterish at heart) all got to play at the park and was a nice experience.
For the record, I am not Pants' first wife. But this is what we did. We wanted Brookside but it was the 4th of July and the city uses the park.
I supposed having Hickory Park cater the wedding and rehearsal dinner may be a bit overkill, huh?
