Stayed over at resort town (2,3)

Ross

I believe the answer is:

on ice

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

'stayed over' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'resort town' is the wordplay.
I cannot really understand how this works, but
'resort' could be 'nice' (French coastal resort) and 'nice' is found within the answer.
A single letter 'o' remains which might be clued in a way I don't see.
This explanation may well be incorrect...

'at' acts as a link.

Can you help me to learn more?
