My sister's family did the cave tubing and had a very good time. They had a slight delay with a bus breaking down, however a replacement was brought in quickly and they continued with the day. The caves were very nice and the provided lunch was also a big hit. They would recommend this excursion.
We stayed at the port area and wandered in some of the shops.
We went to the market and checked out some of the local art work. We were only in port for a short time since it began to pour rain.
