Girl to change hotel (5)
I believe the answer is:
edith
'girl' is the definition.
(I've seen this before)
'change hotel' is the wordplay.
'change' becomes 'edit' (edit can mean to change or alter).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'edit'+'h'='EDITH'
'to' is the link.
(Other definitions for edith that I've seen before include "and 19 Across: 'Little Sparrow'" , "Evans, Sitwell or Piaf" , "- Cavell, WW 1 heroine" , "Dame - Sitwell, English poet (Facade)" , "Female name" .)
