If you really want to go you should make a reservation in late 2008.
We made our reservations in Feb '08 for this years meeting and had to settle for a Days Inn in Council Bluffs Iowa. It wasn't too far from the meeting, but we could only get a smoking room and the place was in the truckstop and casino district.
It isn't the best place to stay.
If you're not a shareholder you can buy tickets directly from BRK on eBay. This year they sold them for $5 + $3 shipping.
If you go there with an open mind you won't be disappointed. If you go there wanting stock tips then you will be disappointed.
