My husband and I just got married and are planning a stop in the Maldives as part of our honeymoon. I don't have first hand experience, but what I've gathered is that as long as we stay out of the capital or non-resort areas we'd be fine. For the kind of money your expected to spend, the resort staff better not care.
Edit: Here is a helpful article from Passport magazine (which is geared toward gay travelers).
