Supongo que ya es tarde para la respuesta pero ahí va igual. South Friars me pareció una de las playas más lindas del Caribe. El taxi cuesta 4 dólares por persona en taxis colectivos.

Taxi from port cost $7pp. All of you will feet in one car. Taxi stops on Carambola beach club. Sun beds cost $10 pp and shared umbrella(good size) also $10. They give you wristband and you could also use facilities (from 9am there is a person checking wristband at front of restrooms). Drinks at bar are $10 for cocktails and $4 for local beer. You will need to arrange pick up time to port. Water at see was shallow and clean. You could snorkel on right side of the beach. This is a Caribbean side and water was warmer.

Didn’t see any, there are some at Cockleshell

Depends on how much driving you plan to do. We were on a cruise stop and only travelled from the port to South Friars and back by taxi. A car rental didn't make sense for us.

Approx 15-20 drive. Enjoying the scenery we didn't worry. After passing through the port security, walking into the main shopping square, we arranged our mini bus. Price depended upon how many in the mini bus. It didn't take long to find sufficent numbers. We agreed a pick-up time and found the driver waiting for us.

There are several taxis waiting at the port. You can share a van with others or there are smaller vehicles for singles or couples. You can arrange a return pick-up with your driver and pay him on the return to the cruise ship. This ensures that the driver will come back for you.

There are several places to get a drink there. Shipwreck Beach bar is very popular on the far end of South Friars Beach (about a 10 minute walk from Carambola). We stayed at Discovery Beach bar in the middle of the two and had great food and a much smaller, more relaxed visit than either of the other two larger places (heavenly). There are also several other places, but they were shut down. Carambola is the biggest and most commercial place of the 3. Discovery is the little quaint local beach bar, and Shipwreck is in the middle in terms of size and facilities.
