So that's a tough question, partially because it depends on when you are traveling. If it's in the near future, it's hard to say what programs and activities at AKL will actually be running. If it's in the future when things are more back to "normal", honestly you could spend a whole day at AKL and not do everything. I found I had to get out of the mindset of experiencing a certain amount of things anywhere in Disney to feel something was worthwhile. You can absolutely do a lot at AKL in an afternoon/evening and be able to enjoy the resort, but it really depends on what your goals are/what things you REALLY want to experience. Some things are only held at certain times, and may not be available in the late afternoon/evening...other things (like the savannah night viewing) only happen after dusk. I don't have a link to an activities list but I think you can find them pretty easily online....take a look at that and figure out if what you want to get out of the resort can be done in the limited time you have.
