I think it will be fine. It will be cold, but sunny - dress appropriately. The lights are up, and they're beautiful. I can't really recommend any specific restaurant in the park, as we usually end up eating something from one of the stands within the park - curly fries and corn dogs, etc. I think the TN tornado closes if the temp is below 45. Get some hand warmers, etc. I think you will enjoy it. There are some deals for season passes now, you can upgrade your day pass for the rest of this season and next season, for a really reasonable price, if you live close enough to come a couple of times within the next year. Heck, I live 10 minutes away and I STILL need to get over there before they close for the year! We did get our $$ worth by using our passes at Splash Country, though!
Funny about it previously being Silver Dollar City - my husband worked at Dollywood when it was SDC - the only thing remaining at DW from SDC is the Blazing Fury ride!
