Flamingo's are not native to the island, and can only be found in one spot. That spot is Renaissance Island which is owned by Marriott. If you stay at the Renaissance, admittance to the island is complimentary with your stay, and the water taxi can be boarded at the docks, or inside the hotel lobby. You read right, the boat comes inside the hotel lobby. Since we were staying at the Marriott Surf Club, we did have to pay $125/person to have the joyful experience of playing with the flamingos. Included in that fee was lunch and a drink at the restaurant located on the Island. One tip to remember is that if the Renaissance is fully booked, you won't have the option to purchase this day pass. It is only available if the hotel is at 80% capacity or less. So if this is an excursion you are determined to do, I would recommend staying at least one night at the Renaissance so that you're sure to get your chance to visit the Island.
