We are staying at the Beaches resort next week. My 16yo son is interested in the resort/intro course for scuba. Can anyone share details on course - like how long it takes and what to expect for diving. Will he be able to do the 2 tank dives, or just 1? Once we pay the initial fee for the course, the dives are included, correct? Will he be able to dive every day, if he wants? Is it safe for him to go out with the dive group on his own? Thanks everyone.
