Activity for Marissa

We're having an outdoor ceremony and an Indoor reception on the water. We will have full access to the grass area and My fiancé came up with the idea of getting a bouncy house for the kids that will be attending our wedding....is that tacky?

I would like to have a kids table at my wedding. Set up with coloring books and little activities. My question is...I have maybe 6 teenagers attending my wedding...what kind of table should I set up for them?
