The Lincolnshire Marriott has a theater and a couple of restaurants, but the property REALLY shows its age, IMO. It's in need of a total overhaul, starting with the tattered carpeting.
The pool is okay--fine for a regular Marriott but extremely un-resort-like. They have a small room with videogames for the kids. The gym is well-stocked (including a Smith machine!) but has a very goofy, retrofitted layout.
