Bath is a nice place and a decent campus, definitely worth going for a look, it's not really that big a trip in the grand scheme of things, London to Bath, shouldn't take any more than 2 hours or so? Can always stay over at a hotel if you're worried about being tired or anything like that.
Interview is an entirely normal part of the application process at many unis too, don't worry about it, nothing sinister going on![]()
Paddington to Bath is 1.5 hours on the train, so not far in the grand scheme of things at all.
Also, I went to Bath so would deffo recommend it
