Our training shop was a grass roof hut on a beach, only visible from the beach. We were lucky, we decided to cut our evening short on vacation, and find the actual location of the dive op the day before.
Missing people in our class, the next day.
Our 2nd boat ride after cert, was buried in a maze marina at the wrong slip.
Apparently, even with massive giant tanks of helium onsite, flying a balloon is too hard to pull off. A hot dog stand has more sense than that.
After certifying the next 4 weeks of scuba vacations was riddled with dive shop "kiosks" nearly impossible to find, boats in marina mazes, 3rd world addresses, manditory phone check in in a country our phones failed in, useless cab drivers, and not ONE single dive op that can put GPS coordinates on their website.
