It is so hard to judge on a few hours look round with rubbish weather and building work. Back in the day I remember not wanting to go to Kent because it had snowed and I was cold all day when I looked round. The course was secondary to the weather and feel I got!
When choosing DD secondary school we just did not feel it on the open evening for the school we chose. It was pouring with rain, really busy and we could barely move, the school was shabby and cold, the girl who took us around was unenthusiastic. However, we chose it as it had great results, reputation and was logistically closer (walking distance rather than a 50 minute bus ride away to the school that impressed). DD had a fantastic 7 years there. We are so glad we did not chose the school based on the 1.5hr look round. Your feel for the place has so much baring on who shows you round and the weather on the day.
Go for the course first. The university experience will be made by the people your DD lives and studies with not the buildings/weather.
