Is it better to travel to Greece alone or with a group?

I recommend you to travel freely in Greece, because it is easy to play with a group, but the tour is just a cursory tour, without depth, and you can't play well, but the free tour is a place where many tour groups don't go, where you can taste a lot of food and experience Greek culture more deeply, so I recommend you to travel freely, that's all.
