What sentence is correct and why:
I spent my holiday at the seaside.
I spent my holidays at the seaside.
I spent my holiday at the seaside.
I spent my holidays at the seaside.
or
Where do you want to go for a holiday?
Where do you want to go for holidays?
Where do you want to go for a holiday?
Where do you want to go for holidays?
I would choose the second option, with holidays being plural but I often came across the singular form of this word and now I'm not so sure anymore.
