I enjoyed lighthouse a bit more than Turneffe, possibly the difference between a sunny day and a rainy day, but I think Lighthouse was prettier. When you are at the BH on the surface, it looks like you are just anchored in the middle of nowhere, not very impressive unless you are either flying over or underwater. I might do the trip again, just snorkel the BH and do the other 2 dives.
Before going to AC, my wife was convinced every shark ever born was issued a picture of her with an attack on site notice. Now she is usually first in the water.

Been there, done that, the washing machine ate the T-shirt
