plan an entire solo weekend

Around last year, I had to spend 2 weeks in Cambridge, England, for my work. As it was complicated to go back to Paris for the week-end, I chose to stay there for the week end.
On the saturday, I went to London to visit (well it was mainly walking around and shopping). I spent the evening in my Cambridge hotel with a bath (and the spa things i bought), pizza and a movie. On sunday, I visited Cambridge.
