The easiest way to HDD is to take Disney transportation to the Magic Kingdom, and then take the Resort Launch (boat) to Ft Wilderness - when you get off the boat, follow the signs to Pioneer Hall, it is a very short walk.
It all depends on where you are when you leave to go to these reservations. If you are at a Disney Resort the free way would be to go to a park and take the resort bus (or boat if at the Magic Kingdom for Fort wilderness) to the resorts where your reservation are at. If you are at the park again the buses or boat would get you where you need to go.
If you don't want the hassle of catching the Disney transport then using a taxi or uber to get to Animal Kingdom Lodge might be less hassle if you want to pay. To get to Fort Wilderness for the Hoop De Doo, there really isn't an advantage to taking a taxi, as where it drops you off you will still need to take a bus to the area where the Hoop De Doo is located. I would take a boat from the Magic Kingdom to Fort Wilderness to the Hoop de Doo.
Sanaa: If you're at a park, take a bus to AKL. If at your resort, take a bus to AK and transfer to the AKL bus.
HDDR: If at a park, take a bus (or monorail, if at Epcot) to MK. Transfer to the FW resort launch. OR take a bus to FW and transfer to the internal bus to Pioneer Hall.
If you're at your resort, bus to MK and launch to FW.
