Light drinkers welcoming quiet holiday destinations (8)

I believe the answer is:

sunspots

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

'welcoming quiet holiday destinations' is the definition.
Although both the answer and definition are plural nouns, I don't see how they can define each other.

'light drinkers' is the wordplay.
'light' becomes 'sun' (sun is a kind of light).
'drinkers' becomes 'spots' (I can't explain this - if you can you should believe this answer much more).
'sun'+'spots'='SUNSPOTS'

Can you help me to learn more?

I've seen this clue in The Independent.
