Where on the gulf are you going. The beaches are still open and only a few tar balls have shown up so far. Here in Florida the chamber of commerce is running ads telling people not to worry the beaches are OK and no oil. I would check with the chamber of commerce of the area where you are going. The media has effectively destroyed the tourist season here for no reason the beaches are fine so far. Also alot of the resorts are doing a live view of the beaches t prove it is ok
