Need a new vehicle!

My family is multiplying overnight and the thought of it overwhelms me. I'm getting married in May and my fiancé has 2 kids. His son is in a booster and daughter in a car seat. And my daughter is in a car seat. Plus I'm 3 days late now sowho knows where that will lead! I need a vehicle that will seat 7. There is no way I'm going to her two car seats and a booster in my sedan. My budget isn't a lot because I'm going to be upside down on my current vehicle a little but I'm going to have to get something bigger. Anyone have an opinion, good or bad, on anything? I don't really want a minivan but I'm open to it. Also, I commute so gas mileage is an issue too.  

Chevy Traverse seats 7. My MIL just bought one almost a year ago brand new. We all love it.

I have a Chrysler town and country. Love it. Decent gas mileage, too.

My husband and I are trying not to get a minivan either but my best friend loves hers! And we took are Jeep into Chrysler one time to get a tune up and the sales lady demonstrated the Town&Country Sto&Go for us... we were both jaw dropped. I would buy THAT minivan. But I hear ya, we need a bigger vehicle too, we have a VW rabbit and a 3rd baby on the way.
