We are looking at getting the City Twinner by Baby Jogger. No one stocks it but we did see today the Twinner II. Same stroller except for the front wheel vs swivel wheel City Twinner has.
Unbelieveable how light and easy to push 2 kids in. We pushed about 75 lbs (2 kids) in the store with ease. Even with the one front wheel it was simple. No lifting. Took it outside, same thing. WOW.
Now it was time to colapse it. Not too bad once you get the hang of it. Three pins, swing two bars and close. The 'tiny' problem I found was if you hold the stroller sideways like shown on the Baby Jogger webpage, the front wheel swings back and forth. I found holding it upside down kept everything together. I guess you can bungee the wheel to the base if need be or buy the bag to hold it.
So bottom line we like it. Only concern is traveling on the buses or monorail. The stoller is light and generall compact but it's tall when closed. I'm sure we can get on the buses but I'll be no help with the 3 kids. This is our main drawback. But I think the pros out weigh the cons, i think. Rather have my own stoller than pay each time to rent one. Especially when we go to Disney every year and sometimes more.
With most stoller weight limits kinda low, this stoller can handle 150 combined lbs. Heck it was made for Disney so I'm sure it will be great in the parks.
Good luck.
