We went to the beach on our own. We paid $4 per person for a cab each way and they told us that you didn't have to pay for the beach loungers but that was not true. $10 to rent a lounger and $10 for an umbrella, so $23 to go to the beach, but it was nice. We did not eat but they did offer food and drinks at the beach. I think the cruise offered an excursion with food and drink included- so that might have been a better deal!
Afterward we did a little shopping- very expensive.
