It's so cool your kid maintains that friendship! It's marvelous.
Yes, time marches on. I had a wistful feeling on this cruise. It was only our second, but it hit me how he was growing up, especially seeing all the littles and babies on the Wish. It was a mix of happy he'd found his people in Edge and seeing another small move out of childhood.
I just wanted to add he didn't feel unwelcome in Oceaneers by the new policy. Not at all, if that's a concern for anyone. If the cruise was a longer one, I think he would have floated back to the club and switched between Edge and Oceaneers. The Wish Oceaneers club is really nice. He said he'd built a rollercoaster and then got to ride it in the simulator they have there. I can't remember what it's called, but that was a highlight!
