I was reading up about the free shuttle service through Mears that takes guests to Busch Gardens and in taking the advantage since I will not have a rental. What I want to know is this similar to the SeaWorld bus where you have to get to Univerdal City Walk to get picked up for your trip to Busch Gardens or do you have to take the SeaWorld bus and then transfer from that Park to get to the bus? Has anybody experience in this bus trip to the park?
