snorkeling in french polynesia

Just left a post and had a thought after I completed it. We are looking for the best snorkeling in FP. Will be visiting Moorea, Raiatea, Rangiroa, Huahine, Bora Bora, Niku Hiva. We prefer snorkeling from the beach (if calm and lots to see). Will be on a cruise ship so time will be limited.. 8-10 hours on each island. Are there any hotels that for a fee would let 4 adults use the facilities for 2-4 hours..Chaises , umbrellas (skin-sun issues). Would only be interested in hotels that have really great snorkeling with easy access. We are healthy 60-70 year oldsl

Thank you for any information on this
