Despite the fact I think is great to have multiple things to do at the boat other than the gigs: All-Star Jam, Karaoke, Paintings, etc, I don´t have an once of excitment to watch covers from ACDC, Alice in Chains, Metallica, Deep Purple, Ozzy, etc...
All I care are the Bands and Gigs
I really can understant the reason behind not annoucing bands at this point, if they have bands "booked" under their sleeves(like Undivided Multitude, f. ex).
To generate new interest you need big annoucements(multiples bands or well known bands). For americans it is easier to make a last minute decision to buy the tickets and embark at this awesome expirience. For non americans it is another ball game. Intl airfare, Hotels, VISA(some nationalities). Maybe UMC doesn´t care about "new interest" from the single fan, I really dont know how much business comes from us(the Old Fans) and how much business comes from travel agencies.
