Feel being outside on vacation usually means stay at campsite (3,4)

'stay at campsite' is the definition.
(a guy rope is a camping rope also called a stay)

'feel being outside on vacation usually' is the wordplay.
'feel' becomes 'grope' (I've seen this before).
'being outside' is an insertion indicator.
'on vacation' says to hollow out the word (remove centre letters).
'usually' with its centre removed is 'uy'.
'grope' enclosing 'uy' is 'GUY-ROPE'.

'means' acts as a link.
