We have been to Old Town a number of times when we had a vacation home down the road from there. Nice place with a bunch of small stores and some restaurants. There are a few rides for entertainment also. The complex is built with a two lane road in the middle of it, which accesses the parking area and the stores face the road. When they have the cruise-in the cars then park on this road. (At least that is how they were doing it the last time we were there in 2004). It is right off route 192 and if you do not know the area that is basically the tourist district, so depending on the time of year you can expect a bit of traffic. From TV I think the quickest way to get there would be the FL turnpike to 429 to 192. Time wise maybe 1hr 10min. If you have not seen it they do have a web site:
