Hi, usually not a problem around the adult pool, sometimes the DW and I share a lounger ie one in the pool and one relaxing on the lounger! Around the family pools it can be hard to find a seat. Some people take the chair saving to the extreme. Last time on the Fantasy I was up early on the sea day, around 7 am, went to get a coffee by the pool and I saw a women clipping down her own beach towels with small plastic clips, 2 towels to each of for 4 chairs. Also placed sandals or shoes on each chair and then left. I went for breakfast and to my cabin came back about 90 mins later nobody on the loungers. She was not the only one saving chairs.
