It basically depends on the time of your ADR for 'Ohana and how much time I wanted to allot to get there. There are too many variables for me. I could see times when I would want to use a cab/uber/etc.. so I did not have to leave as soon. Other times, I could see a later morning reservation where I just did not want to stay in the room any longer and would make an adventure of getting there via Epcot or MK.
