What is the best way to get from the Grand Floridian to Sea World??

[aandk1997]

We're planning on going to Sea World one day while we're at Disney World. We are staying at the Grand Floridian. I've noted that there is a "bus" you can catch that will drop you off at the entrance to the parking lot (which means you have to walk through the parking lot to get to the entrance), and then wave down another bus when you leave. This option doesn't sound that appealing.
So.....what's the best way to do this?? One day car rental?? Can this be done at the ticket and transportation center??
Anyone who has done this, please give me some insight as to the best way to do this.

Thanks.

You can get the schedule at the lynx website. It is cheap but a hassle if you ask me. I chose to hire a towncar for about $55 dollars roundtrip. You could also rent a car for just one day.
