We just went to Rhodes Hall last week and it was amazing. If you take a route taxi, the cost is $5 pp for a day pass. You can rent towels for an additional $5. The charge for transportation and a day pass is $20 pp from the beach road., pick up around 9:30 and return at 3:30. They have snorkel gear for rent as well for $5. You won't be disapointed.
