There are some really great mini golf courses in Orlando! Here are some of our favorites:
Tiki Island has a Polynesian theme (International Drive)
Pirates Cove obviously has a pirate theme (3 locations: International Drive, Hwy 192, Crossroads Shopping Center)
River Adventure has a river boat theme (Hwy 192)
Congo River has a jungle theme. They even have live alligators you can feed! (2 locations: International Drive, Hwy 192)
Basically, if you just drive down either International Drive or Hwy 192 in Kissimme, you will see several mini golf places.
They are pretty much all the same price. Around $8 per adult and a little less for kids. Most have a discount if you play again.
