We will be cruising on the new Celebration in March. I don't necessarily want wifi to connect to email or social because I'd be kind of happy to get away from it. What I would like to know is there FREE wifi that will support a simple iMessage? I understand photos, etc likely wouldn't work -- but would feel more comfortable if I could stay connected with home as I have elderly parents. I know we stayed connected last time we cruised, but I think we may have paid for a plan. I don't remember. We are also traveling with others, so it sounds like the Hub App chat will work for that.
