Lunch Boxes provided on Departure


Blocks of rooms set up at the following hotels for the Nitrogen Management Group meeting.  You will need to call the hotels directly and indicate they are part of that group.  The Clarion and Best Western gave reasonable rates, while the Holiday Inn is kind of pricey. The Clarion is the old Holiday Inn which has been renovated, the Best Western is about 2 years old.
Holiday Inn at the Campus (old Ramada across from campus)
1614 Anderson Ave,
Manhattan, KS 66502
Highest priced
Clarion Hotel  (old Holiday Inn off Fort Riley Blvd.)
530 Richards Drive Manhattan, KS 66502
Best Western of Manhattan,  (off US 24 east)
601 Poyntz
Manhattan, KS 66502
Reservations will need to be made at most by July 1 for the blocks.

There are a number of other hotels in the area also, but these are all okay. 

Poster Boards for 24, 45"x45" posters will be available
