Ideal place is available in March? (8)
I believe the answer is:
paradise
'ideal place' is the definition.
(I've seen this before)
'is available in march?' is the wordplay.
'available in' means one lot of letters goes inside another.
'march?' becomes 'parade' ('parade' can be a synonym of 'march').
'is' placed within 'parade' is 'PARADISE'.
(Other definitions for paradise that I've seen before include "one enjoyed before the fall" , "Sensual garden" , "Felicity" , "a state of bliss" , "Shangri-La?" .)
