I've always wondered this. As a family we aren't good at sitting around a pool all day so I wonder what an earth you do all day in a villa
Go to the beach to swim and snorkel, waterpark, read, walk, visit local towns, villages, cities for a wander around, museums, lunch in a nice marina/town square etc, monuments, castles and ruins, vineyards, boat trips or more active things like cycling or diving.
Most days we get out to do something, before a relaxing afternoon reading in the sun with occasional dips in the pool to cool off.
Someone still has to get the stuff out of fridge, cupboard etc, someone still has to lay table, plate up food, make coffee, then soneone has to clear it away, package it back up, load dishwasher, wipe surfaces
But that 'someone' doesn't always have to be the same person. You share the load.
