Hi - I did Natural Sciences at Cambridge many moons ago. It was very hard work and stressful at times. I had a great time though and made many close friends with whom I'm still in touch. I met some amazing people and it is incredible to see what some of them have achieved since college. The whole experience helped me to get on to my chosen career ladder and I feel like I have had a stimulating, interesting career (which I currently do part time as I want to spend time with my young family). Although I had many misgivings at the time I am really glad I went and I am very proud of my Cambridge degree.
I think some of the reasons stated above are very poor reasons for making a major life decision. Has she spent time actually really talking to students? I think that would be the best way to address these points. All the points are valid concerns but I am not sure she has got to the bottom of any of them yet.
The lunch point is a complete non-starter. I am vegetarian and didn't enjoy the college meals very much. I thought they were horrible. I just bought / made my own lunch. I had a pretty good kitchen for 2 of my 3 years. There was a small element of double payment in the first year but the second and third I didn't have to pay for college catering.
I went to very few formal dinners and wore a gown probably 10 times in my entire university career. I didn't really like all the formal, old-fashioned, traditional stuff. I found it annoying and not very me. But attending the odd formal dinner doesn't mean people aren't standing on their own two feet! In fact you usually have to pay extra for a formal dinner so I wouldn't call it 'coat tails'.
Tourists are indeed common in both towns but are most prevalent during the summer when university is not in session. I cannot remember ever having my way from building to building impeded by tourists. They are very rarely allowed inside colleges and colleges are particularly strict around revision and exam time.
The small sizes of the colleges is a valid point. I went to a small college on purpose but some of the larger colleges had intakes of over 200 undergraduates a year. I did find that most of my friends at other universities made many of their friends either through their course or their hall of residence and the sizes of the halls was very similar to the sizes of the Oxbridge colleges.
Not sure exactly what she means about tutors but by the time I was in my second and third years my supervisors were all from other colleges chosen for the specialties not the college they were in. In the first year the courses are all so general it is not necessary to have very specialised tuition.
If these are the genuine reasons she doesn't want to apply, I think she is probably making a mistake because she may have the wrong end of the stick on at least some of the issues. If there is more to it and there are other deeper reasons for her not wanting to apply then it would make sense to tease them out and it may well be absolutely correct not to apply.
