I believe the answer is:

intrusion

I'm a little stuck... Click here to teach me more about this clue!

'unwelcome visit' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?

'our inn it's upset' is the wordplay.
'upset' indicates an anagram.
'our'+'inn'+'its'='ourinnits'
'ourinnits' is an anagram of 'INTRUSION'.

'getting' is the link.

Can you help me to learn more?

(Other definitions for intrusion that I've seen before include "Encroachment" , "Uninvited presence" , "Something entering undesirably" .)
