A couple of ideas that worked well for us on our cruises.
- Take a small power bar as there are only a limited amount of wall plugs. Maybe a small ext. cord.
- Take an over the door shoe holder to keep all of your loose items in rather than all over the small table tops.
- clothes pins, bungee cord, bathroom freshener, .
- soft sided cooler, tip the steward and it will be full of ice every day (must keep the wine chilled) large zip bags for ice.
- Stainless steel wine glasses (won't leave home without them), corkscrew and plug.
- binoculars (for looking at Cuba when you sail past) The Americans on board go over the top when passing Cuba!
hope this helps!
