No, its not the same person all the time, so I guess in that respect they do have some free time. I guess with a lab project its only necessary to come to the lab to do the research, especially if you can do all the data analysis and lit reviews etc at home. It's just really a case of finding the right balance. My supervisor is the same one who I'm doing my dissertation with, so we know each other quite well which I hope will make things easier if I'm having trouble with things. And she also has a good track record and I'm sure she doesnt want me there 24/7.
