I really prefer night diving to day diving. Would like to know if there are any liveaboards or dive shops that do more than 1 night dive per day.
I think your best bet is to go someplace with good onsite shore diving where the pool is always open. As previously mentioned, Bonaire and Cocoview are what jump to mind, I think Cocoview would work well, the setup is good for it and you can get a good variety of shore dives from that one spot. Places in Bonaire you'd have to check if/when they lock things up. A few places on Grand Cayman might work. Sunset House you get tanks while the shop is open and put them in your locker for later - you might need an extra locker.) Coconut Bay, Lighthouse Point? - I don't know their routines as far as doing something like this. The previous shop at Turtle Reef would let you label and leave out tanks for night dives after they were closed, though there would be no rinse tanks or anything later. I think after hours people would also come in with tanks from elsewhere and dive there. That might all be the same with Sundivers there now.
Might be a place or 2 in Curacao that would work, like a few apartments and condos serviced by Go West diving - perhaps All West apartments, or maybe Marazul - I'm not familiar with how convenient 24x7 tank and gear availability is there, but it might work. (At their main shop at Kura Hulanda night diving is less convenient than it might be. Unless somethings has changed you have to move your gear to a different locker a small distance away for the evening as they lock the gear room, as well as squirreling away all the tanks you need too. Probably doable, but you'd want to talk to them.)
I think the closest you'll get on a liveaboard is a duskish dive and a night dive, but hard to imagine one that does more than one each night. Even if you find a boat that frequently sits on a dive site for the evening instead of heading for a sheltered mooring for the night, the procedure on most is to have a couple staff on deck watching in case of a problem. So I doubt you'd find one keen on you diving all night. (The crew needs to sleep sometime.) Organized dives with shops, whether shore or boat, you're lucky if there is one each night, often only 1-2 scheduled in a week.
You might google some of the specialty night diving things , like fluorescent night diving. Maybe someone, someplace, offers a specialty trip that focuses on night more, though I've not seen such a thing. (You could always get into organizing trips and see if you can find enough vampire types to fill such a thing.
