JC - I just re-read your post with the mention of Green Bay. That's another real possibility. Plenty big enough airport.
My quickie check on the web shows a Regency Suites in GB with 223 rooms. 8 meeting rooms w/ a total capacity of 2600. There's also a Radisson and 2 Holiday Inns each with 120+ capacity. Many others I didn't check.
Door County encompasses the south side of the Bay - lots of great lighthousing and other touristy attractions in the Door area.
Just need to pick a weekend when the Packers have an away game.
Rgds,
