Of course you can do what you want, but people throw "half day park" around when discussing AK as it's pure fact and there simply isn't enough to do. That's the difference and is why I take exception. We aren't talking about an inane argument of doing 1 favorite ride and calling it done "for you." I truly believe you can objectively list the offerings and objectively state there is enough there to make it a full day.
AK could be bigger, with more to do, sure. They are working on that. However, flat out skipping major portions of the park because it's your prerogative, actually doesn't make the park a half day park objectively. You're right, it makes it a _____ day park for you. I just think it's unreasonable. There is a lot of subjectivity on this argument, but there is one thing we can agree upon. You can measure all the "activities" in any park, pretty objectively. If there were a park with literally 1 ride and 1 show, you could more easily make the argument there isn't enough to do. I don't believe AK is in this position with the offerings currently there.
AK is only open about 7 - 10 hrs on a typical day. If you list the activities, shows, trails, attractions, food, etc...you'll find there is objectively enough to do to make a day or more out of it. Whether or not you like them and want to see the show, walk the trails, or ride the attractions is a different argument.
