You win on this one. You should not try reserving deck chairs. That topic is a hot button around here, and on cruise ships. Some people put books or towels on a deck chair, and then disappear for hours at a time, eating, exercising, going to other activities, etc. Obviously, this is not fair and not allowed. Many passengers and pool attendants as well will remove such things from a chair if no one has come back to it in a reasonable amount of time, say 20-25 minutes. Some people legitimately leave their chair to get a drink at the bar or grab lunch at the buffet, but anything longer than that is unfair, and, frankly, obnoxious.
