is it the same thing with Oxford? should I visit some other time?
I don't think so. But there are different opening times for different colleges and sometimes wedding and other parties on the premises so no visitors are allowed in at the time. So you may not be able to see all the colleges but I am sure you will still be able to visit quite a few. And the grandest of them, Christ Church will definitely be open as it incorporates the Cathedral where the service is celebrated on most days.
