The portal is a great idea for a time that has long gone. You put something like that in any town in Britain or Ireland and it will just attract the scum. The fact that the people behind it didn't for see such ballbag behaviour is mind boggling. The only type of place for it is at another attraction that you have to pay in for and that would help keep out most (but not all) idiots but it kind of then defeats the purpose of the idea.
