Where there’s visible direction to the hotel (6)
I believe the answer is:
harrow
'where' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'visible direction to the hotel' is the wordplay.
'visible direction' becomes 'arrow' (I am not sure about this - if you are sure you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'the hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'arrow' after 'h' is 'HARROW'.
'there's' acts as a link.
Can you help me to learn more?
(Other definitions for harrow that I've seen before include "A school; agricultural implement" , "It breaks up clods and covers seeds" , "worry" , "Till" , "and another [SCHOO]" .)
