Bachelorette Party in Southwest MI or Chicago--Need hotel in a Lake Michigan town. Any ideas?!

I am planning the bachelorette party for my best friend, and I'm struggling to find hotels in a lake town that doesn't require us to stay more than two nights. She only wants to go for one. We are thinking about staying in South Haven, Grand Haven, Saugatuck, but we are flexible and open to any ideas along the Lake Michigan coast. Any Michigan or Illinois girls know of any hotels in Saugatuck that would be great for this kind of thing? Or any other suggestions?
