i have two marathons, and i find that they fit in a lot of places that an infant seat won't.
what kind of car do you have? i have put two RF marathons outboard in my BILs civic, and they fit well. there wasn't any room for any other passengers, but the two carseats fit perfectly.
personally, if i'm going to buy a britax, i'm not going to get the roundabout unless i get a really good deal on it. it's a great seat, but for $50 more i can have a marathon which will last so much longer.
