I dive out of Eilat a lot (northern Red Sea), so different routes than a Hurghada liveaboard, but the same water type. Agree this is mostly wide-angle country for that itinerary. Wrecks and reef walls are the main show. If you're thinning the bag after Indonesia, leave the macro kit home. I shoot a phone in a housing and a GoPro with no strobes, which forces the keep-it-simple habit. What I'd actually want on a Red Sea boat: a camera you can grab every dive without fuss, a spare battery or two, and hands free for buoyancy. Agree with the two-wetsuits tip already in the thread for November. Beyond that I'd rather leave options I won't open at home.
