We were there at a relatively slow time in January and I wouldn't assume that you can show up whenever you want and have 50 chairs open. There might not even be 50 chairs at the adult pool. We got there right around the time the pool opened most days and every day we were the only people there for an hour or two. But, by the afternoon almost every chair was taken. On one occasion there wasn't a single chair available. Maybe there was an unusual amount of adult couples traveling at that time.
