I'm fine with current, I'm also ok with swell. I loved the Maldives. It's just side mount adds challenges sometimes, fighting with bungees, bolt snaps, long hoses, other divers don't appreciate you eitherI don't think you need to worry about entry and exit for side mount. Most boats will do their very best to put you in the water in the best conditions. I have done the trip a few times and I think they have always been on one of the Damai boats. Luckily I have always had great conditions (crossing fingers and praying to the Goddess of the sea for good conditions) but I know it can get a little hairy. It is basically a relocation trip that can only be done during certain times of the year. I have heard stories about boats getting stuck in Banda etc. Are you doing an Alor - Ambon trip, Saumlaki - Saumlaki, or Kupang -? etc.? Which boat?
Everything depends on the divers on your boat and the CD (cruise director)etc. We have had great experiences but have encountered some current (totally manageable and worth it) in the hopes of finding the hammerheads. I was on another boat and the CD said she would never take divers on the hammerhead dives in Forgotten or Banda because she didn't want to worry about them. I made a mental note to never ever book a Banda trip with them. So If you have a bunch of people who don't like any current etc... Either way it is still a great trip, its just a so much better with hammers and snakes! oh and thankfully for us the hammers were never deep. Banda is amazing fishy and really fun! Enjoy!

I'm on blue manta, I've been with them before, they're a top outfit who look after you. I like diving with Egoi and crew, so all good on that front.
