Eastern and/or Western Caribbean cabin mate platonic (16 - 38 days)

Looking for a cabin mate (platonic) for a Caribbean cruise to the Eastern and/or Western Caribbean. Depending on how much time is available, we could combine 2 cruises. I am male, 61 years old, widowed, non-smoker, experienced traveler, have traveled to over 80 countries, normally travel on my own. In the Caribbean, it makes sense to use the cruise ship as a means of transport and hotel. However, I would organize the excursions on site myself, as well as book all flights and transfers. Everyone pays for themselves, but we share the cabin and common activities, of course. Tui Mein Schiff is a good option, as they sail from the Dominican Republic into both the Eastern and Western Caribbean. There is a week between the two cruises, which can be used for a beach holiday or for exploring the Dominican Republic. If you don't have 35 days, we could also do just one cruise and add beach days. I am flexible with cabin choice, whether it's an inside cabin, outside cabin, or balcony cabin. I'm usually not in the cabin for long, mostly just for showering, changing, or sleeping. Destinations in the Caribbean: Eastern Caribbean: St. Lucia, Barbados, Grenada, St. Vincent and the Grenadines, Martinique, Guadeloupe, Dominica, Sint Maarten, St. Kitts and Nevis (Caribbean Islands with MeinSchiff 2) Western Caribbean: Jamaica, Mexico, Belize, Honduras, Costa Rica, Panama, Colombia (Best of Central America with Mein Schiff 1) We can gladly coordinate what we do. I would find it nice if we did excursions together and went out for meals/drinks on the ship. Everyone should also have their own personal space. You should be interested in the country and its people and participate in the planning. Foreign language skills and a driver's license would be very helpful. You must be a non-smoker.
