Need advice: Honeymooning in February

We're planning our honeymoon for February and want to travel somewhere with a tropical climate and beaches. We also want to be able to do activities while we're there (not just sit around at the resort). What are some good places to consider? We're planning on going for 10 days.

Side note – we really wanted to do Fiji but found out it would be their wet season… if anyone has visited Fiji in February and can share any feedback that'd be helpful too!
