I've been to Branson many times, and I have never thought of it as cheesy. We'll be going again this summer. We're going to spend 2 days at Silver Dollar City. We're going to see Dolly Parton's Dixie Stampede (saw that show once before ... fabulous!) We'll probably just spend some time at the pool and maybe play some putt putt.
If you want to go out on the lake, there are several places where you can rent a kayak or canoe. I would never think of bringing my own. It would cost more to transport it than it would to rent it for an hour or two.
I live in central Illinois, and there are lots of "touristy" things to do in Missouri and Illinois. It really depends on what types of things you enjoy doing. We've done trips to Kansas City, St. Louis, Chicago. I enjoy living in a smaller community and going to larger cities for vacations. I love museums and Major League Baseball games (Go, Cubs, Go!), so I tend to think of my vacations in terms of those types of attractions. If I was planning to go to California, I'd plan my dates around when the Cubs would be in town!!!
So, what types of things do you enjoy doing? There are lakes and boat rentals everywhere, so that part is easy.
