We walked to Royal Palms on Seven Mile beach from the port. That's about as cheap as you can get It was about 2 miles. No entrance fee to the beach, it's public and free. We rented 3 loungers and an umbrella from Royal Palms, the sign stated $10 each but the guy only charged us $20 total. Beers and lunch were expensive compared to other islands but it was so beautiful there I didn't care, Ha ha. We took a taxi back and it was $4 each. Lots of taxi's right at the resort waiting for fares back to the ships.
