If you only had a week to spend in the Bahamas, where would you go?  Before saying I should plan a longer stay, I would if I could.

You don't say whether you are traveling by boat or not but my vote would be Tahiti Beach, Elbow Key, Abacos. Quiet, pristine and beautiful.

Depends a lot on what you like to do.
 Marinas and restaruants – Nassau, Harbour Island, Freeport or the Abacos.
Get away from it all (or most of it anyway) – Exumas, the Berry Islands and parts of the Abacos.
Bit of both in your time frame – straight to Nassau, over to the Berry's then finish off in Bimini before heading back over.
Get a taste of it all – Bimini, Gun Key, Cat Key area. 
Of course all this would depend on where you would be crossing from and the weather.

My vote is the Abacos for the March/April time frame. Close by and lots of  options from vacant islands to great settlements and towns. One week could be a GREAT cruise.
BUT, you need to allow for weather, as if it is blowing out of the  north, which is usual in winter, you can not cross, and must wait. Thus, if you  only have one week, best not to try to cross the gulf streram in the winter  months.
I recommend crossing from Lake Worth inlet to Old Bahama Bay at West End.  Short trip to a great marina and cooperative customs. Then proceed to the  Abacos.
