Best Destinations in February-March

We are planning our honeymoon during February end or March beginning.

Please recommend the best Beach destinations couple friendly and not in peak season.

I have researched about Mikanos, Greece and Okinawa,Japan.

Looks like Mikanos is mostly closed during this time of the year.

And I need more info from someone who has been to Okinawa during February or March.

I would love to have more suggestions which I could research.

We are from India.
