We have been checking flights from Florida to Abacos. Quotations have been
$400+ return.

Does anyone know if this is normal, or are there less expensive fares?

Ideally, we would like to fly to Treasure Cay, but Marsh Harbour would also
be OK.

If we are driving, a more northerly Departure would be preferable - Maybe
Daytona. If flying in, Miami or Lauderdale would be OK.
