100% recommend - 5 days of training in a row felt intense, by the end of the third day, we were feeling it, they do treat you like an athlete there.
The private week is tailored to your requirements with a private coach - for me, more technical i.e. bandeja, dropshot, serve, glass.
The groups do more high intensity drills if that's what you're after? Though I met a lot of people who did both weeks because they loved it so much and got different things out of it.
