Whew, the new strollers are small and $$$!!!
My neices and nephews werent that comfortable in them for sleeping at all...they were 2, 4, 6. we actually brought and umbrella stroller and rented a single for the 4 year old figuring when the 6 year old pooped out at night, we could carry the 2 year old.....welll......the new strollers are pretty upright, and hard as a rock, no scootching room like the old big ones! So when the 2 and 4 year olds needed a little nap, they sat in the umbrella stroller, it was actually more comfortable for them.
Also, if they do fall asleep in a rental stroller, guess what? You either have to wake them up or carry them to the car or bus!!! Holding the 49lb 4 year old was really HARD!!!!! he was so tired, I was able to wake him up at least to walk from the ferry boat stop onto the boat and then off the boat and into the line for the tram where he then crashed and I had to pick him up...then there was the walk from the ferry stop to the end of the row where our car was parked (the 6 year old got the umbrella stroller for that hike since she was the heaviest)......it was really difficult at 10 at night with everyone being so tired!!!!
Have FUN!!!!!
