Thanks for the suggestion. Any reason why Adventureland first?
Because Saturday is a Morning Magic day, the park will already have lot of people in it when you enter. But they are in Fantasyland and Tomorrowland. So you can escape that early crowd by going to attractions like Indy, Haunted Mansion and Big Thunder. If you want to do Space or Peter Pan right away you will get there and it will already have a sizable line.
A few things I want to see for sure are Electronica and World of Color (viewing location not important) since they are new to me.
For ElecTRONica watch the LaserMan show. For WoC location is very important unless you are very tall. Get there early to you color group's meeting place and once in the park take a spot on any tier as long as it's against a rail. So nobody is blocking your view.
I also read that due to passholders sometimes Fridays are more crowded than Saturdays lately.
Not exactly the whole truth. Friday is a regular day until 5pm when local AP holders show up after work and the park gets crowded. But this Month Fridays are extra busy because of Halloween Parties. Saturday are always busy, but using the early and late hours helps out.
16 hours at the parks... I think I could still do it... with much coffee of course.
It can be a lot of walking and a long day. Take an early afternoon break if you need it. If not able to get back to a bed, there are some nice chairs in the Grand Californian lobby that people have been known to nap on.
Do you know if there is a list of where and what each of the Halloween themed food it located at? I see photos here and there on here from people, but not a list yet.
