I am the hotel package coordinator for Welcome To Rockville, which is a two day festival featuring Marilyn Manson, Korn, Slipknot, Ministry, Suicidal Tendencies, and my more non-theremin playing Rock acts.
Packages are sold out but I have two buyers who are trying sell their packages because they are unable to attend.

Let me know if you are interested and I will put you in touch with them.
