I can't see why there should be a problem, as I said before we have had visits from potential applicants, flight crew, cabin crew,
flying clubs, RAF etc.
For the second interviews a visit to an ATC Unit is encouraged ( at least it was when I applied ). Manchester is a good unit for people to look round as you can see both the airport side and area. I need to check the exact procedure for visits given recent "events", but by all means leave a post or pm me with as much notice as you can.
