We just returned from a family cruise to Alaska aboard Quantum OTS. It was truly wonderful with one exception that I think parents need to be aware of. The message function in the RC App is not usable for kids under 13! Both my 11 and 12 year old grandchildren were admitted to the teen group (“The Living Room”) so they were allowed to come and go as they pleased. They essentially could have the run of the ship until the 1AM curfew. Thankfully they are very sensible and well behaved kids, BUT they had no way to communicate with their parents or grandparents or visa versa. I asked Guest Services if there was some kind of work around and was told there was not, and they have had others raise similar concerns. Hopefully RC will make a change. BTW, We’ve been home for over a week and have yet to receive the famous post-cruise survey.
