Chair hogs. Perhaps no one draws the ire of cruisers more than the person that goes down early in the morning and puts a towel down to reserve a prime location by the pool… only to leave it for hours. Yes, you are allowed to save chairs on Carnival, but the official rules are for only 40 minutes — enough time to go grab a bite to eat. After that time the cruise line employees can remove your items to let someone sit in the chair.
