River borders dilapidated retail and holiday accommodation (7,4)

I believe the answer is:

trailer tent

I'm a little stuck... Click here to teach me more about this clue!

'holiday accommodation' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'river borders dilapidated retail' is the wordplay.
'river' becomes 'trent' (River Trent).
'borders' is an insertion indicator (inserted letters are bordered by others).
'dilapidated' is an anagram indicator.
'retail' anagrammed gives 'ailert'.
'trent' placed around 'ailert' is 'TRAILER TENT'.

'and' is the link.

Can you help me to learn more?
