Me & my friend are having a joint birthday party with our friends because my birthday is the day before hers. We're planning on having it in the evening & allowing kids to go too since all our friends have kids we also thought it would save others finding a babysitter & that it would be nice for the kids to celebrate it with us. Trouble is. We cant think of a theme! Venue is a bit of a problem too because the place has to allow at least 20 of us including children aged 3-5yrs. An outside area for the kids would be nice for them but the other problem is food wise. Do we hire a hall & do the food or do we go to a restaurant or pub? Once the venue & food is in order i think the biggest problem will be the theme. It'll be my 21st & her 25th. So we need something fun especially since the group of friends that we're with are all slightly on the loopy side. we'd like to have the kids join in with the theme too. Any help?
