OK, if you are staying on Disney Property you may pick up your Hoop De Doo Tickets at any Guest Services at any Walt Disney World owned resort hotel, or you can arrive an hour early and pick them up at Fort Wilderness' Pioneer Hall. You cannot pick up your tickets at Guest Relations or Will Call... they are not on the same ticket system.
The easiest way to get there is to drive, however you can get a bus to their from any park or DTD. Just hop on the bus going to Fort Wilderness. If you go to a later show and ride the bus, you will have to take a bus going to DTD and transfer to a bus your to your Disney Owned resort there. If you are staying in the Swan or Dolphin, you can do the same. If you are staying at a Good neighbor resort on Hotel Plaza Blvd, you can do the same, but you will have to pick up that bus in the bus loop in front of the McDonald's... this is also where SoG picks up.
Hope this helps!
