OLCC is a very nice resort with lots of amenities - multiple pools, tennis courts, two or three golf courses, restaurants, mini-golf, etc. - and several resort sections spread out over a very large piece of property that adjacent to the Animal Kingdom Lodge area of Disney. I believe that the OLCC property is in Kissimmee. We've stayed there three times, I think, over the years and enjoyed our Orange Lake stays.
Its convenience to Universal, however, is a matter of what you think convenience is. In terms of distance, OLCC is roughly 18 miles from the Universal parking garages and I'd expect the drive to take 25 to 30 minutes (depending on traffic conditions, time of day, etc.). There are dozens, quite possibly hundreds, of hotels and resorts that are closer to Universal than OLCC. We've gone to Universal many times while staying at that resort and haven't really thought that we were inconvenienced because of the location. I guess it's a matter of your expectations.
