I know this is late. We heard announcements about chair hogging on our Vista Jan. trip.We've also seen signs absolving Oceania against lost/stolen items around the pool deck(cabin theft issues might constitute potential legal issues.)When we wanted a lounger look for the following "Warm" drink glasses/Towels dry etc, We move right in & take our seats. Stuff left there gets moved, period! Did NOT have a single issue. We did see this woman(one time) try to save all the loungers around us.(about 6)She then left for a while & my spouse took all the towels & such & removed them.This allowed other pax to sit there. She returned about 30 min. later with her entourage & was p/o'd that the seats were now taken except one. When she complained I said sorry, you can't save chairs.
