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, usually 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 their own way, but we will share the cabin and joint activities. Tui Mein Schiff is a good option, as they travel to both the Eastern and Western Caribbean from the Dominican Republic. 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 just do one cruise and add some beach days. I am flexible regarding cabin choice, whether it's an inside cabin, outside cabin, or balcony cabin. I usually don't spend much time in the cabin, 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 MeinSchiff 1) We can discuss what we do. I think it would be 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. Knowledge of foreign languages and a driver's license would be very helpful. You must be a non-smoker.
