I don't know why I keep reading these stroller threads, as my DH has said that there is no way we need another stroller. Yet, I still dream of the "perfect" travel stroller.
I just wanted to chime in on this because we have travelled with many strollers and used both buses, boats and our car.
The main thing with the buses is to have the stroller folded and bags and child in hand when the bus comes. Having said that, 9 times out of 10 we are rushing to the bus,afraid it will leave without us, scrambling to fold up the stroller, forgeting to empty the basket, so the stroller doesn't close right, DH cursing a blue streak, me frantically grabbing the kids and the bags etc, tripping as I enter the bus, kids are crying, I am sweating, DH is not in vacation mood....you get the picture.
But by the end of the trip we were much better. We had a routine so that we knew what I would do and what DH would do in preparing to board the bus. (I actually took over the stroller folding since I was much more practiced at it from home, while he took the kids and the bags.
I have travelled with big heavy strollers both single and double(peg peregos) but most of the time we used a car so there was no pressure to "fold and go". The kids were small and they did great with the extra room for naps, feedings, etc. I loved the reversable handle that I had that was great for the ever changing sun direction.
We also used the lite rider on the buses (note the above description of the boarding process LOL!). With practice it was ok, but a bit heavy to carry on and off the bus. The full recline was great and needed as well as the big basket. The problem was that we would load up the basket only to have to empty it sometimes in a huge rush!
We also used a combi travel savvy. For some reason DH had major issues folding this one (I think the wheels needed to go a certain way). Did not recline all the way, so not as nice as the graco and basket was small. So we hung a lot off the back which was easier to take off when folding.
Well after all this, I guess the thing to do is practice with the strollers, both folding them and lifting them. Also, make sure your spouse knows how to fold the stroller and do not wait until the bus is about to leave to teach him how!! I loaned my combi to my SIL and it came back mangled due to her DH's rushed attempts to fold it when the bus came!
Good luck and let us know how it goes!!
