We have had the urban double by mountain buggy for the last 3+ years and absolutely love it! Go to mountainbuggy.com It's been in sand, in snow, on grass, up and down hill, in the city and rural areas. It has come with everywhere...malls, walks, Disney, zoos, etc. It weighs on the heavy side but its so sturdy and efficient that its worth the hassle. Tow warnings though: you'll need a good size SUV or mini van to store it in. Also, DO NOT waste your money on the infant carrier attachment because it will not leave enough room for you older child to be comfortable. Hope this helps! Good luck.
