Not to pull the sexism card but I'm going to anyhow... would you say this to a 21 year old man? And why would you assume a 21 year old woman is somehow vulnerable in a way that someone not 21/not female might be?
A demeaning assumption, IMO. Although I am sure you meant well.

Personally, I would not want a 21 yo female friend of mine going there alone their first time.
Depending on the particular group, there can be some less-than-savory individuals present. Avoid anyone who goes up to have a court slip signed - they are there by force of law and not by choice.
Not everyone who appears to be a nice is nice.
Trust your instincts.
