Warren Buffett predicts huge crowd at Berkshire Hathaway's annual meeting in May

The crowd at this year's Berkshire Hathaway annual meeting is likely to top 40,000 as the company marks 50 years of Warren Buffett's leadership.

In his annual letter, Buffett urged shareholders to check out Airbnb's website if they are having trouble finding one of Omaha's 14,000 hotel rooms.

Buffett says the Airbnb is making a special effort to sign up people in Omaha willing to rent part or all of their homes.

Buffett has said he hopes Airbnb will help make it easier on shareholders who don't want to pay for the three-night minimum stays some hotels require.

Berkshire also plans to offer shareholders a second day of shopping in the exhibit hall filled with some of the conglomerate's products.
