<human>: Can you condense the text into three sentences or less?

Hey everyone, I'm a 17 year old that has never travelled before. My cousin has invited me to a 1 week trip to Las Vegas, all expenses would be paid for. But, the catch is that the trip will be a mix of work/conventions, as well as free days for fun. There will be dozens of others going from my cousin's workplace, who I know none at all.

I am a very shy introvert-person and it is hard for me to socialize, especially with strangers. My parents have no complaints on the trip and are even ecstatic of the idea of me accepting the offer.

Currently, the only advice is from my dad, who has said: "Even if you don't have fun/know nobody, it's just 1 week. So just go."
<bot>: Been invited to 1 week trip with cousin and cousin's work members(All expenses paid). Will feel terribly uncomfortable, because I don't know anybody or anything.
