I COMPLETELY AGREE with you!
This isn't meant to be an "argument" with anyone in particular who considers them half-day parks; it is just my take on the half-day vs. full-day issue:
I consider them FULL DAY parks. It is IMPOSSIBLE to finish both of those parks in a half-day, unless, of course, you skip half of the attractions!
As it is, when AK does their short, 9-5 hours, I either have to skip some of the attractions or else I feel too rushed on the animal trails, which I enjoy enough to EASILY spend 30-60 minutes on EACH one.
At the Studios, the only days I've ever finished ALL 18 attractions on a full day is when they do the 9 AM - 10 PM hours.
And I'm the type that, if I have the whole day free, is at the parks bright and early, BEFORE Rope Drop!
Realistically, it is just impossible to do EVERYTHING that these parks have to offer in a half-day. Even if the parks are empty and you don't need FPs for ANYTHING, the sheer runtime of all the attractions, if you add up their runtime and allow for walking between each one, would add up to more than half a day!
And then when you take into account eating lunch in the park and any snacks...
And also in a park like the Studios where many of the attractions are shows that are not continuous loaders (Beauty and the Beast, Playhouse Disney, LMA, Indy, etc). They have to be seen at specific times, which often requires backtracking and sometimes leaves you with 15-20 minutes of "dead time", if you have that much time to kill before one of the shows starts, as none of the attractions there can really be experienced in that short a window, without risking missing the beginning of your show.
If anyone can TRULY complete ALL of the following in a "half-day", they should contact Guinness for inclusion in the book of World Records!:
The Great Movie Ride
Rock and Roller Coaster
Tower Of Terror
Star Tours
Muppet Vision
Voyage Of The Little Mermaid
Beauty and the Beast
Playhouse Disney: Live
Magic Of Disney Animation (Main show, exhibits, and drawing class)
Walt Disney: One Man's Dream (WITHOUT Half-arseing the exhibit area)
Toy Story Midway Mania
Narnia
Indy Show
Lights Motors Action
Sounds Dangerous
Backlot Tour/Postride Exhibit
HISTK Movie Set Adventure
American Idol
Anyone care to post a "Touring Plan" showing how it is possible to have ALL of this done before the start of the "3 O' Clock Parade"?
I find it a challenge to fit all this into a FULL day, (going at a reasonable but not an "insanely commando" pace), unless they are doing a 10 PM close! And my list omitted arguably the best attraction in the park, Fantasmic!, as it is a nightime show unavailable in the first half of the day. And I also did not include all the shows that are not always listed as "attractions", such as the Jedi Academy, Mulch Sweat and Shears, High School Musical, etc)
Same thing with AK. Can anyone TRULY say they can do ALL of this before 3 PM, WITHOUT half-arseing the self-guided animal trails?

Again, COMPLETE agreement! And not only is it fine, but for my taste it's the best day parade on property, and has a nice Christmas overlay as well!
