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!
No, the main event of WrestleMania'll be Maven against Kamala the Ugandan Giant! And then Sting will come down and burst into flames for no apparant reason! And the Nation of Domination will...uh... I don't know! Who cares?!
