Yeah that was really helpful... seeing as you'll be there on a weekend... D'OH!

The only one I can find that's less than an hour's drive or so is Sunshine Beach State High School, Ben Lexcen Dr, Fri 5.30-6.00pm
If you feel the need to go for a nice drive in the country, there are 3 or 4 other classes about an hour out of Tewantin on Saturday and Sunday.
