overall I enjoy the trip. it is well organized and efficient. Things go as described. However, there is certain information that you should be aware in advance. The activities can be physically intense, so opt out if you are not fit enough. In addition, the guides will not take care of us personally. You should be able to follow the group. They will separate us into 4 groups, 15 people each, to do 3 activities; sandboarding for 2 groups together while snorkeling and kayaking 1 group. There is only 1 guide for sandboarding and kayaking while 2 for snorkeling plus jet ski to make sure everyone alright. It takes around 30 min - 1 hour per each activity. I was lucky that the group started with sandboarding and then snorkeling and kayaking, so after get wet can just change. Lunch is make your own wrap type, so you can choose what you like, plus potato chips and chocolate chip cookies. Toilets on the island are not good and no shower room, so make sure to use toilet on the ferry and bring your towel. We saw the whale from the ferry, so watch out. The group before us saw 3 turtles during snorkeling, but we didn’t - lots of fish though. Be careful of shipwreck and coral as it can be shallow and difficult to move. Also kayaking was relatively short, all these due to strong current which is understandable.
