TL is very close to OKW. The OKW/Typhoon/DD bus runs about every 20 minutes. In the morning and early PM, it stops at TL before heading to DD and in the late afternoon it stops at TL after stopping at DD. This minimizes the travel time in wet suits, etc.
If you will have a car to drive, it is about a 5 minute trip to TL from OKW. (Turn left onto Community Drive, Left onto Bonnett Creek Pkwy, Left onto Buena Vista Drive and right into TL -across from the entrance to Cirque.)
The bus is pretty efficient, so the personal auto is certainly optional. It all depends on your own travel expectations.
Enjoy!
