Drifts by trendy holiday resort (6,4)

I believe the answer is:

cruise ship

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

'holiday resort' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'drifts by trendy' is the wordplay.
'drifts by' becomes 'cruises' (I can't explain this - if you can you should give a lot more credence to this answer).
'trendy' becomes 'hip' (both can mean fashionable).
'cruises'+'hip'='CRUISE SHIP'

Can you help me to learn more?

I've seen this clue in The Daily Express.
