It all depends on what you find relaxing.
We saw that Picard liked to relax on the holodeck with a Dixon Hill murder mystery, or sometimes a nice gentle trot though the countryside on a horse.
We've seen that Dax liked to use the holosuites to get massages and spa treatments and that Kira sometimes uses them to meditate. Paris uses them to spend some quite time in an Irish village or to work on a muscle car.
Bashir and O'Brien, on the other hand, enjoy a good planefight in the skys of Britain, a James Bond adventure, and having their asses kicked at the Alamo.
To each their own.
