Sin Cara posted his hotel key on his official Twitter account, revealing he's staying in a room at The Westin Jersey City Newport hotel in Jersey City.
Given the fact the company usually books all of their talent in one hotel over Wrestlemania weekend, it's likely this is the WWE hotel. There are no vacancies, however, you might be able to get some autographs by hanging around. Below is Cara's card:
Good night world! Look what I just received, my hotel key for Wrestlemania, very cool no?? Have a good night 4sq.com/14DH4ep
