Hi,
I went on this boat a couple of years ago and it was the most boring thing i have done on a holiday .... EVER !!!
These excursions are usually aimed at Germans (well they were all German on my boat) but the boat ride really is not worth the money ... they take you up the coast to Mogan .. let you jump into the water and then give you the worst lunch ive ever seen ... also play drinking games as well .. but we had had enough by this point and went to the very back of the boat.
Wouldnt recommend this .. there are other things that are much better to do than this ... Total Waste of Time !!
