I will give you in this article some Destinations that I have thought would interest you if what you are looking for is a cruise for your honeymoon, one that is authentically romantic. But be told in advance, You don't have to get married or have a partner to enjoy any of them.
If the beaches are your thing and you want to recharge your batteries without hesitation, your option is the Caribbean or Polynesia. If you want to link history to the beaches, then I would think of the Mediterranean coast. If you decide together with the romantic to mix the adventure or the exotic, then from Japan to Egypt or South Africa. I will try to give you some touches of these cruises, but as I always say, the important thing is you. There is always a destination for every couple.
If you are lovers of sun, the beach, sunsets and tranquility then your perfect destination is the CaribbeanYou can make a stopover in Cartagena, Puerto San Cristóbal in the Panama Canal, Puerto Limón in Costa Rica, Cozumel in Mexico and Fort Lauderdale in Florida ... to give you just one example.
If you want to enjoy that same paradise but adding something exotic, then a cruise through Polynesia, With a stopover in Moorea, Huahine Bora Bora, Maupiti or Tahaa, it is your most romantic honeymoon.
If you want to add history to the beautiful beaches, I think Mediterranean cruises are your best option. I'm talking about discovering Malta, Greece, the medieval buildings of Sicily, Naples, Croatia and the Côte d'Azur. Although if it is about history, I would not rule out a trip across the Nile, from Luxor to Aswan, or the cities of Central Europe. Any of these river cruises can help you.
If adventure is your thing then I would suggest a cruise to Alaska, or the South of Chile and Argentina. You will have the opportunity to discover the majesty of its landscapes and glaciers.
