Grand Tetons and White Water Rafting

My husband and I are thinking about going out to Jackson Hole in late July. We would like to do some white water rafting for a few days and then stay in a B%26amp;B for a few days.

Can anyone recommend a rafting a company that does overnight trips?

Also, are there any B%26amp;B%26#39;s or small inns that people really like?

One last question - how are the crowds in late July?

Thanks.
