Advice for dropping off resumes/ doing interviews

I'm moving to work in Whistler (the mecca of Canadian snowboarding) this year and need to find a new job ASAP. I've been working at the same place for a year now so I'm a bit rusty when it comes to dropping off resumes and applying for jobs. I'm just wondering if any of you have some advice, seeing as the majority of you probably have more experience and knowledge than myself. I'm mainly just afraid of coming across as being too childish or being judged solely on my age (I'm 18). Tips, tricks, any advice you may have would be greatly appreciated.

Thanks,
