What is a great PRIVATE secluded romantic beach destination for vacation?

[hsfieldhockey]

So I am trying to find a vacation for:

2 people
Beach Vacation
Non-touristy
Romantic
Warm
From Boston Logan Airport
TOTAL Vacation Price Doesn't Exceed $1600 (includes flight and hotel)
For a minimum of 5 days

Can you recommend any places/destinations and give me the rates for how much it would cost for everything?

It would either be for travel in January, March, or May (preferably the earlier the month, the better)

Depends on which beach you want to see in which part of the world

here are a few options -
