Thanks to everyone that took time to answer my question. I have visited the recommended link to the store and plan to make the trip there. I must admit that once informed that I was planning to drag a guitar along on the cruise, my wife ...., well, I'm lucky to still be walking.
I did purchase an older Yamaha fg-75 with the intention of taking it along, but still undecided if it's worth the effort to drag it along. Perhaps I'll take a week vacation from playing too.
