Resort on the right is more pleasant (5)
I believe the answer is:
nicer
'more pleasant' is the definition.
('nice' is associated in meaning with 'pleasant')
'resort on the right' is the wordplay.
'resort' becomes 'nice' (French coastal resort).
'on' says to put letters next to each other.
'the right' becomes 'R' (common abbreviation).
'nice'+'r'='NICER'
'is' is the link.
(Other definitions for nicer that I've seen before include "Even more 7 down!" , "harder to please" , "improved" , "More pleasant or fine" , "more likeable" .)
