So….this was posted on the Mayhem Cruise website:

Unfortunately, due to circumstances beyond our control, we have been forced to cancel the Mayhem Festival Cruise. If you purchased a cruise package, you will be automatically refunded to the credit card you used to purchase. If you used a prepaid card or gift card to purchase the cruise, please contact Rose Tours for your refund (215-663-8800). If you used a credit or debit card, you will see the credit within the next 2 to 3 weeks.

We are also offering anyone who purchased a cruise ticket a lifetime complimentary pass to the Rockstar Energy Drink Mayhem Festival Summer Tour. You will still receive your cruise refund in addition to the lifetime pass to the Rockstar Energy Drink Mayhem Festival Tour. This pass is valid on any tour date beginning in 2013. Details on getting these lifetime passes will be announced shortly.

We apologize for the cancellation.

This sure is a bummer. Anytime I talked to a band or fan about this cruise over the past couple of months told me how siked they were or wished they could go. The upside to this is a full refund and lifetime passes being issued to the future Mayhem fests (Touring act, not cruise).
