The piano department where I did my undergrad had its own separate bank of practice rooms that were a somewhat comfortable temp, each with a small Steinway grand. You had to go to the front desk every week and reserve a specific room and block of time.
It annoyed me greatly that another piano major who was in my year would reserve 2-hour blocks, but mostly drink tea and chat with her friends with occasional moments of touching the instrument, while I actually wanted to practice.
