I was only partially impressed with my trip aboard the Cayman Aggressor IV in February.

Although the accommodation and food was great and the staff were undeniably pleasant, I didn’t feel that they went above and beyond on our trip as they were described as doing in previous reviews I had read.

The staff didn’t seem all that interested in interacting with the liveaboard guests, however that shouldn’t detract from the great experience of being oboard a great boat in a beautiful location.

The diving was very good and enjoyable too.

Recommended for: A relaxing and enjoyable vacation overall

Although the diving didn’t differ hugely from one site to the next, I still really enjoyed my experience on board the Cayman Aggressor IV.

The staff were helpful, the food was delicious and plentiful and the accommodation was perfectly suited to my needs.

Spending time on board was such a relaxing experience as you got to travel between the scenic islands and enjoy the surroundings from the sun deck which was a great way to pass the time in between dives.

It was also an added benefit to be able to create your own schedule, only diving when you felt like it and relaxing when you pleased.

Recommended for: Flexible schedule and great location
