Age range of Great Wolf Lodge in Washington?

Hi, my parents have planned a summer vacation to Great Wolf Lodge in Washington, I haven't done much research but in the pictures on the website, (besides the "teen room" or gr8 space as they call it...) it looks like it's filled with kids... I'm 15 and would really like to know if teens go there too, you know, whether to be prepared to be attacked by little kids or being prepared to chill
