I brought 2 single strollers for my kids who were 1 and 3 at the time. The only time I used both was at Key West when we walked to the pirate museum. It was very hot and easier to keep the kids close by strapped into the stroller. After riding in the plane my three year old didn't want to sit in a stroller so he walked. I primarily used my techno xt on the ship around dinner time. My 1 year old sometimes needed to be walked around and fell asleep during dinner and I was able to park it right next to me in the dining room. (We were lucky that our table placement left enough room for the stroller not to be in the way) When we got to CC, I didn't want sand in my stroller wheels so we walked off the ship and I snagged a wagon which they have for free to borrow. It was quite a walk until we got to the wagon area, just about to the family beach, but I threw the kids and beach bags in and they rode the rest of the way while we found a spot. It is very tricky to get the stroller out of the room while the kid is in it, I recomend setting it up outside before you set your child in it. The doors are soooo heavy and slam shut and it is nearly impossible to turn the stroller around in the room, or hold the door with one hand while pushing over the threshold with the other. Looking back, I wouldn't have bothered with the second stroller because the three year old only used it once and I could have just borrowed a ship stroller for that time. Hope that helps.
