I rented a City Mini for my trip in Feb. The double. My wife was in charge of getting herself and the kids on the bus. My kids were 17 months and four. And, I will say, even if the bus was crowded, someone was always willing to give up a seat so my wife could sit with the children. I found the City Mini easy to fold and I usually stood near the back exit of the bus with the stroller to keep the aisle clear for other passengers. It was fairly crowded when I went and I had no problems. Oh, I reserved the stroller about 14 days out. I also ordered a case of water to keep in the room to avoid having to pay food court/gift shop prices.
