Although a frequent visitor to SXM, I haven't yet stayed at Club O. I know non-guests of the resort can rent the umbrella and chairs, but for guests, are they included in the rental price?

If you stay at Club O, your chairs and umbrella are included in the price of your stay. You are provided with a tag for each chair. The tag has your abbreviated name and check out date. You can then locate your favorite place on the beach, find your lounger and attach the tags. Then you can relax, knowing each day your loungers are reserved for you.
