Las Vegas IRS Forum this year

[tilt]

For several years we've gone to the IRS forum in Las Vegas held at the Rio. Unfortunately, we were not able to go to Vegas this year. I know it was held at Mandalay Bay. For those who have attended both, what was your feeling about Mandalay Bay? Were there improvements in traffic flow? Did you find it difficult to learn new layouts? Any real problems? We're looking forward to going in 2010 and are interested in your comments and impressions. Thank you.
