How to say "we will have fun"
I want say that we will have fun on holidays but I am not sure how to say it. Could someone help? This is my attempt: En general, nos divertiremos.

As you are now asking questions it would be helpful if you added your level in Spanish and English to your profile. The 'effort' you have made is not in the future tense - you could just use vamos a divertirnos.but are you 'looking forward' to what you expect to be a good holiday, or are you saying 'let's have fun on holiday - or is it an order ie we will have fun on holiday?
You can use 'pasarlo bien' to have a good time.
without more context and some idea of your language level I will leave this for a hispanohablante
