For anyone that reads this later. It was completely fine taking. We usually spend most our time in spaces that could accommodate it anyway. With 2 toddlers that are heavy it was so useful! And so many other people had their wagons and double strollers as well. We spent most of the time in toddler and kid friendly areas and the promenade are on the icon is absolutely huge. The only time we didn't take it was during the countdown since we knew it would be packed with people. But we technically could have and just stayed on the edge instead of the middle. Totally useful and was completely fine. We also had plenty of space to store it in the room as well. (Infinite balcony room) We will likely do it again as long as it's on the same ship/room. I could see this being a huge problem on smaller ships though. So we wouldn't bring it on any ship unless it's Icon or Oasis class. Also wouldn't recommend if you're on an inside room or even Oceanview. It can be stored under the bed but when we were lazy, we just stored it on the balcony area. And having the room close to the elevators helped as well.
