Fill with delight in admission (8)
I believe the answer is:
entrance
I believe this is a double definition.
'fill with delight' is the first definition.
(I've seen this before)
'admission' is the second definition.
(I've seen this in another clue)
'in' is the link.
(Other definitions for entrance that I've seen before include "Vestibule" , "Fill with wonder, door" , "Bowl over" , "it's common, say, for some children to sit" , "Send" .)
