I’m in Mexico , I’ts not Belize but the diving here is great, , no problem or extra fee’s for singles, my airport code is ZLO, it’s 160 mi south of Puerto Vallarta, a very safe area. Dive shop is owned by a single female, there are apartments that divers like right behind the dive shop, shop is on a bus route, we have beach diving as well as boat and we have a ship wreck only 23 feet deep water today is 80 deg
