The Belle of Branson Steamboat ride, dinner and show was very enjoyable for me and wife and is about 2hrs long with a ride on the river.
The zip lines just north of Branson was a nice couple hours w/lunch adventure.
Springfield's Bass Pro Shop (grandfather of all) is a huge store with a look at all the trophies, fish tank and get some take home collectables.
We always like going to the amusement park just outside of Branson where they have rides, shows, old-time soap making and many shops from a bygone era to see products made right on site. (damn if I can now remember this place as haven't been to Branson in about 10yrs).
Really enjoyed the history of the Titanic Museum, and the dinner/entertainment of Dolly Parton's Western Show.
If still playing, there is a real cool Chinese acrobatic show worth seeing.
