i don,t have any weekends. i must work in my store. how poor！

I'll be meeting with my family at my home on Saturday before some of my family members return back to their home in a different state. Then I'll be relaxing in my language studies at home on Sunday. Where are you going to spend your weekend?

"Where are you going to spend your weekend?" This is the normal way to say it. Of course, we understand "where u gonna...?" but it sounds like you failed school and are on the streets. I mean, if you want people to think you're a little stupid and rude, then by all means type this way - I shan't stop you. To answer your question, I've been invited on a short bicycle tour to a nearby village for a wine festival. Look up "Petrov Plže" and you'll see where I will be. :)
