The cave was better than I expected! It's so crazy! It was cool to see monkeys as well, and the buffet was amazing.
Please note that most of your day will be spend waiting around. It is very easy to lose your driver/van/guide/group/boat! It is very disorganized! You will be told one thing and then told another! You might wait 30 min, might wait 3 hours! The tourism board/coast guard/TPTB has a way of doing things that takes forever and is unorganized and the tour guides have no power over it.
