Saw this on the Website today. Don't remember this being there last year.
Silver Dollar City is excited to offer our guests free WiFi throughout the entire park! Use it to download our mobile app and plan your visit!
It's easy to access the free WiFi when you're at Silver Dollar CIty:
1.Visit the WiFi setting on your cellular device
2.Select *SDC Guest* from the list
3.Log in using your email address or Facebook login
IIRC I thought they had free wifi there for the last several years.
I have used their WIFI for a couple of years.. Not a strong signal everywhere, but pretty reliable park wide..
