Fitting a Stroller for Twins (Roof rack?)

[daveymac]

Last year we picked up a 2012 Yaris SE - love it. It's a great A-to-B commuter that's a little more fun than most at a great price.

This summer we learned we're expecting twins. Twins...

We're excited, but the strollers we like don't fit into the trunk at all and the car seats we've tried seem like tight fits, too. I was wondering if anyone's got any roof rack recommendations that might include a case or bag of 30" x 40" x 15" dimensions or if anyone with a couple of kids have some other tips.

One kid is one thing, two at once is another. I'd like to keep the Yaris, but need to make it work. Thanks for the time!
