This was my first (but certainly not last) liveaboard experience. The crew of the Philippine Siren are top row, attending to our every need getting in the water, underwater, and all things topside.
A couple of suggestions: when mentioning the opportunity for a massage, remind guests to share times, on our trip one diver booked herself every day which limited times for others. Another suggestion is to make the dibe guides more distinguishable underwater, i.e. two differentcolor fins, or a bright colored beanie
