I don’t know how you can improve on that trip. The Cayman Aggressor was my 1st live aboard. It is still the best. Don’t pass on Sting Ray City - still one of my favorite dives. It is eat,sleep and dive. One thing you might think about is taking an Rx of antibiotics and antibiotic ear drops. I do that on every trip and have never used them but just in case you won’t be back to shore until Fri.
