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

'it's bound to include all' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'stay at an hotel' is the wordplay.
I cannot quite see how this works, but
'stay' could be 'visit' (visit is a kind of stay) and 'visit' is located in the answer.
This explanation may well be incorrect...

'who' acts as a link.

Can you help me to learn more?

(Another definition for visitors book that I've seen is " Sib took visor (anag.)".)

I've seen this clue in The Globe and Mail.
