I know there is a sticky, but how do you usually get to Universal Studios for just a one-day visit? Staying at Bay Lake Towers and Don't know if we want to rent a car.
if you buy ground transfers, added to your cruise, through the cruise line, they come with your cruise ticket/voucher book. If not, you can purchase them at the DCL bus desk, before you board the DCL buses (this is in the disney welcome center at the airport- just ask the cast members waving the mickey hands, at the bottom of the escalator, heading to baggage claim/ground transportation- get to the correct side of the orlando airport- and there you are (far right, as I recall)).
Neat disney DCL, character orientation video onboard, as you ride! (going and coming)
