Can you guess how much we pay for 4 (or 5) nights per person? Less. No, far less. There is even a game room. And a hot tub. And yes, there are still some spare beds remaining!
Location 1 (7 mostly large bedrooms), for Monday and Tuesday night (and Sunday, when you want to)
And location 2 (10 bedrooms) for Wednesday and Thursday night.
Total costs, per person per night? €20. Less if more people join.
