Stay too long, missing good cruise ship (5)
I believe the answer is:
liner
'cruise ship' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for liner that I've seen before include "may be demonstrated by make-up artist" , "eg QE2" , "Cosmetic item - Titanic, for example" , "QE2, perhaps" , "Material applied to inner surface" .)
