Paul, Did you notice the HDMI inputs on the side of the wall mounted TV?
By any chance di you hear of anyone utilizing them for a DVD input? They might not be activated.
This is something I also regularly check for, and no, there were no HDMI inputs available to the passenger. They very rarely are any more.
But with the movies on demand being FREE you really don't need a portable DVD player (unless it is for your kids or something).
Dancers are usually very picky about the dance facilities, (the right kind of wood floor, for example) so it is nice to know you approve. Do you plan to try a Holland America Dancing with the Stars cruise?
