Yes just for the day @chopc. Now on the (painfully slow as you can't travel on the fast train til after 7pm on a weekday without selling a kidney) train home.
We had the loveliest day. A good look around - even inside the buildings and through doors at eg lecture theatres- culminating in a trip to Beit hall, one of DS's choices, which is home to the SU bar - and happened to have the lady who runs it all and all their events sat outside who struck up a conversation. I think DS was very impressed with all the events they have planned for freshers week (x2, as they weren't able to do a 'proper' freshers last year they are doing both a 'welcome' week and a 'welcome back' week- should be fun!
Very pretty hall with a lovely central quad, as well as were his other two choices with lots of green space outside- and of course Hyde Park across the road. I'm so pleased we visited, it was so much better IRL than any of the online stuff we'd seen.
So after a quick shopping trip we were ready to come home when the flipping Cambridge email re adjustment landed. No place for him. I'm sort of annoyed we even applied as feel it put a slight dampener on the lovely day - but honestly so glad we visited imperial as he really was sold on it and I think would have picked it over C on the basis that he's doing a pure MSci physics at Imperial as opposed to NatSci at Cambridge and he's really ready to leave bio and Chem in the past. He is also very keen to be in London.
So I think we are all good- as I say, slightly annoyed that C impinged as we were in a good place but I guess if he hadn't have tried adjustment we'd always have wondered 'what if'?
Glad that journey is finally over however (unlike my train home that'll be another hour at least 
)
