We put a deposit down on a concierge stateroom for a summer 2016 cruise which I then switched to a March 2017 cruise . . . which I then switched to a December 2016 cruise. It looks like we are switching again. I'm just wondering, how long can I keep transferring this deposit?! I know after 24 months I will lose the onboard booking perks, which is fine. I just don't want to lose the deposit! Thanks for any info!
