The two times I've been to Krazy Lobster in Oct 2021 and May 2022, the taxis are a set $4.00 per person. The massages on the beach are $10 for 30 minutes or $20 for an hour. I did negotiate for some of the souvenirs from the vendors.
I went to The Krazy Lobster FB page and messaged the owner Mauricio asking if they would be open the day we were in port. He responded in a timely fashion and asked how many in our party. I do think you could just go to The Krazy Lobster without contacting them but it gave me a sense of comfort.
Lunch of lobster, rice and corn was yummy. Margaritas tasty and frapped up well.
I just felt a sense of peacefulness with the breezes playing through the palm trees. Water was protected from the seagrass with nets.
Having said that, I have read about Jamie's at The Blue Reef. Sounds pretty nifty as well but I don't know if they have the beach massage. I almost fell asleep, it was so relaxing. Here are some Krazy Lobster pics:
