I didn't book an excursion. I went to the taxi stand and got a taxi to The Krazy Lobster ($4 per person) then was walked to a table on the beach. Basically a DIY. There are vendors there but I felt they respected my "no thank you" and moved on. The beach massages were great and at $20 per hour, a bargain! Lunch was order off the menu. We split lobster ($20) which had rice, veggies and tortillas. Yummy margaritas were very smoothly frapped up. Easily got a taxi to take us back to port. Let me know if you have questions.
