You have nothing to worry about on the parking at Fall Creek (or in Branson altogether), but you are about 5-10 minutes away from the main strip and the restaurants. You should plan on driving your own car, for sure.
Very few restaurants are nearby (and the ones that are nearby are not recommended). Danna's Barbecue is a short drive from the resort and it's good. Many recommend the restaurant at the local college - it's called the Keeter Center.
Fall Creek resort is located on Lake Taneycomo (which actually is more like a wide river instead of a lake). It's good for trout fishing and/or a boat ride, but not much else.
As I mentioned in your previous post, you should plan to take the kids to SDC for a day (at least). The magic show is good for kids and the Moses production is highly recommended (previous past year's episodes were Joseph and Jonah). You are also a short drive from the dam and the fish hatchery. The kids may enjoy that, and then there is the multi-million dollar visitor center which is directly across the highway from the fish hatchery, and then over the dam. Table Rock State park is over there too and it's also the docking port of the Showboat Branson Belle - which the kids may enjoy also.
