My boys love it. We have 3 boys 6, 4, and 11 months and they fit great. We haven't taken it on a long trip yet, so I can't comment there. We typically take our Sequoia for the long trips. The Sequoia is quite comfortable
But for roominess, it is quite good even with car seats. My only complaint is that the rear doors sometimes make it awkward for them to get out. When I see that coming, they just jump over the front seat. They love that at this age anyways, so it works out.
