The walk way goes from between buildings 53/54 and follows the canal to the back of DD. If you follow to the left at the end, you come to the back of Rainforest Cafe, if you follow to the right, you can cross the CDC parking lot and be in PI. It takes about 10 minutes and is not bug infested in December. We don't travel much in the summer, and I didn't take the path in September.
