It sounds like, from another cabana thread on here, that new restrooms have been added towards the end so hopefully you shouldn't have too long of a walk no matter which cabana you stay in. When we had #20, which was second from the end, my then 6 year old and 11 year old walked back and forth every time they wanted food, or needed to use the restroom or pick something up from the shops. I can't remember exactly but I would estimate my 6 year old walked there and back at least 5 or 6 times and she was tired that day. It wasn't ideal but she could handle it, so your older kids should be fine. Now, the way it's supposed to work is you should be able to call a CM to come pick you up and give you a ride to go get food or go to the shops or restrooms but the day we were there we couldn't find any when we needed one and after waiting for half an hour after pushing the call button we just decided to walk. When all is said and done, I'd still book a high numbered cabana in a heartbeat because it makes a big difference for our family. And really, unless you have mobility issues, it's not that far. The cabanas are maybe around 10 - 20 steps apart, some closer than others, and there are only 21 of them on the family beach. That's a very, very rough estimate but gives you a very general idea of the walking distance between #1 and #21.
