I'm driving the four/five hours (depending on traffic) and then driving back home. Or staying with a friend that lives in the LA area. No help to you, I know. I'm not aware of any travel packages, or even an on-sale date.
There was a little bit of discussion on W about this here (The W).
I would think that if you want to attend all the events & have the money to spend on it, go for it! You do get guaranteed tickets for the show, rather than having to scramble at TicketMaster. (Hint: Ticketmaster was a nightmare for Judgement Day last May, & that was an SD-only PPV, which sold out.) And I'd pretty much agree with Mr Shh's cost breakdown in the previous thread. Go for it!
