readings at party’s

So this is a question kinda I guess. I'm relatively new to tarot (ca. 3 years) and my friends know about it. A close friend is turning 20 soon and asked me to do readings at her party (a small gathering not something gigantic). I'm not sure tho cause I never did something like this. Do you guys think it's a good chance to gather more experience or do you think it's not a good idea. And if yes is there something I need to know?
