reader question of the week #2

reader question of the week #2:

"Our little family has 3 birthdays within 1.5 weeks of each other - mine, my husband's and our oldest daughter's. I was thinking of throwing a party to celebrate all of our birthdays - for close friends and their kids. We don't have a lot of space and we don't have a Wii. In the past when we've thrown family parties, we just sent out a bunch of invites thinking only a fraction of the people would show up, but instead almost everyone does. Any ideas on a theme and/or fun activities to keep everyone entertained and the party moving? We live in New England so an outdoor party is not in the cards. Thanks! -Nisa"
