If you are into classic cars, there is an informal car show on Friday or Saturday nights.
Most of the shops are touristy, but there is no admission fee to the area [there are fees for the rides and the haunted hourse], so you don't lose any $$$ just by looking.
Last year we spent an hour or two walking around there on our arrival night, then headed over to a nearby Bennigans (or Ruby Tursday or some such chain place) nearby for dinner.
