I have the City Mini double. I love it! I had to really look into getting a double as well even though my kids are 3 years apart. My oldest has to be contained in a stroller or else I'd never get anything done. The only draw back to ours is that it takes up a lot of trunk space. Other than that, we love it. I think we did look into the one you are thinking about but we didn't get it because of the age difference. Since your two are closer in age, it might work out. Another thing to consider (someone else had suggested this), is to bring your oldest to the store when you go check out the double. (Unless of course you've done that, then never mind.) It really helped us to see how functional a double stroller would be for us.
