If you didn't wait then congrats. You must have gotten on the bus right before it was ready to leave. Everyone else had likely been waiting 45-60 minutes. Nearly everyone I have ever talked to has had very long waits. Occasionally I meet someone who had little to no wait but they admit that the bus was already there waiting for a while before they got on. I'd rather have a rental car. We park hop a lot, go to CW beach, shop around Orlando, etc. And we do not take WDW transportation other than the DS ferry, the ferry across SSL, and a single monorail trip. Our car does not just sit in the resort parking lot.
Now that they are charging for parking I will rent a car and stay off-site and still save nearly $400-$500.
