Respected guide meets excursion group going back inside (8)
I believe the answer is:
Here is my best explanation:
'respected' is the definition.
('esteem' can be a synonym of 'respect')
'guide meets excursion group going back inside' is the subsidiary indication.
'inside' indicates a hidden word.
'going back' says the letters should be written in reverse.
'demeetse' is hidden within 'guide meets excursion group'.
'demeetse' backwards is 'esteemed'.
(Other definitions for esteemed that I've seen before include "Thought highly of, say customer", "Regarded highly", "Highly thought of, respected", "Respected, admired", "Had great respect for", "Well thought of", "Highly respected like good customer", "Honoured", "Highly admired" and "Meet seed being thought well of".)
