Respected guide meets excursion group going back inside (8)
I believe the answer is:
esteemed
'respected' is the definition.
('esteem' can be a synonym of 'respect')
'guide meets excursion group going back inside' is the wordplay.
'inside' indicates a hidden word.
'going back' says the letters should be written in reverse.
'demeetse' is hidden within 'guide meets excursion group'.
'demeetse' back-to-front is 'ESTEEMED'.
(Other definitions for esteemed that I've seen before include "Held in high regard, as customer may be" , "Highly regarded" , "Thought highly of, say customer" , "Highly thought of, respected" , "Respected and appreciated like customer" .)
