Cody:
There are lots of positive points to using
Disney transportation while on vacation at the resort: you can relax and let someone else do the navigating, no one has to be a designated driver in your party if you choose to imbibe, and you get dropped off much closer to the entrances of the theme parks than if you drove and parked.
With all that said, though, our family typically drives to all of the theme parks if our only option is bus transportation with the exception being the Magic Kingdom which is always faster by any form of Disney transportation including a bus. We choose to drive because 1) we're not first-timers (Disney has minimal directional signage) 2) I like to leave the parks by lunch time and find fewer buses running and 3) I prefer not to wait at the bus stops when I could be driving.
With a resort the size of
Caribbean Beach, the bus makes multiple stops. Although this only adds about 5 to 7 minutes usually, I find myself wanting to save time by driving my own car. Most of all, because you will already have your own car and parking at the theme parks is free for resort guests, I recommend driving to all of them except for the Magic Kingdom.
Wishing y'all a magical vacation!
