I'll be there for a week from the 3rd - 11th April (Easter).....can't wait!
Spent a week there in September '08 havn't been back since. We got some good trout and most other reef species, spanish, tuna, and snapper (which was a surprise).
Takes a while finding productive spots though especially if you're new to the area, but we managed a good couple days fishing out around the islands. The current roars up there so if you can it's best you go on smaller tides.
This trip we expect most reef species (excludining snapper as from what I gather they only venture up that way in winter), hopefully some good spanish and possibly try for some GT's.
What size boat do you intend to bring up? Make sure your trailer is top notch coz the dirt roads can be bad. But you should be right if you take it easy.
