I'm not "worried" in the least, just getting aggravated at their poor business plan - there are cabins not sold out, why not announce bands ASAP to draw the most interest and allow for people organizing vacation dates from work if needed?
Even if somehow we did end up with only 28 bands, this lineup already looks comparable to last time. It will be a great time, and the bands are only half the equation in that.
Also, the complaining about big bands is starting to get to me...Nightwish is MORE headliner material than any artist on board last year in terms of drawing power and records sold. You might not like them, but I think everyone needs to acknowledge their status. I seriously doubt they'd have anyone much bigger than Nightwish. UMC can pay the fee for the concert, but the marquee bands like Motorhead or whatever would milk a lot more money to be on the cruise for a business week.
