Question

Are these two sentences natural?

Someone is going on vacation, a party etc.

I know these "Have a great time!" ,  "Have a blast!"

But if I say,
Have much joy!
I wish you have much joy.

Answer

The first two examples are very common. The second two examples with the word 'joy' are not commonly used in the US in my experience.

Answer

Have much joy is not natural in everyday English.
I wish you have much joy is also not natural.
Natural alternatives that match the meaning are:
Have a great time.
I hope you have a lot of joy.
I wish you lots of joy.

Answer

Native speakers wouldn’t use “joy” in this way.
