Interesting responses - thank you! I am actually disappointed that the first bus of the day didn't pick up until 8:40am (or was that not the first bus?)... I was under the impression that buses started running an hour before park opening.
I'm getting my transpo times from a source I can't remember and the Unofficial Guide:
BUSES FROM ANIMAL KINGDOM LODGE:
Magic Kingdom: 12 miles, 15-20 mins; UO: 36 is typical, 51 bad day
Blizzard Beach: 2.5 miles, 5-10 mins; UO: 27 is typical, 39 bad day
Epcot: 8 miles, 10-15 mins; UO: 29 is typical, 40 bad day
Hollywood Studios: 6 miles, 10-15 mins; UO: 26 is typical, 37 bad day
Animal Kingdom: 2 miles, 5-7 mins; UO: 10 is typical, 17 bad day
So I'm going on "worst case scenario" from MK (51 mins) so that I'll be pleasantly surprised if it's less. Our last 3 days we will be at AKL, the crowd levels will be high (Fri, Sat & Sun of Memorial Weekend), so I am bracing myself.
Thanks again - I would love any/all opinions on this!
