What you actually pay for varies more than the listings let on, and it comes down to two models. Some clubs charge a flat day pass: it covers a lounger, the pool, and a set amount of food and drinks, sometimes all-inclusive. Others let you walk in free but set a minimum spend at the bar or restaurant, so your chair is really paid for through lunch and a couple of rounds. A handful tack on a separate fee for a lounger or palapa on top of whatever you order. None of this is a scam as long as you know it before you sit down, so ask one question at the entrance: is this a paid pass or a minimum spend, what's included, and is there a charge for the chair. Sort that out up front and there's no surprise at checkout.
