It seems that most of you posting are fans of DAK and so am I. Depending on what type of entertainment you enjoy definately matters when it comes to this park.
If you like to sit back and be entertained then Magic Kingdom is for you. Add some education along with entertainment and you've got Epcot and the Studios. If you like to hunt for your fun, then Animal Kingdom is your beast.
While I love just about all aspects of ALL the parks, I find the subtle beauty of DAK to be my favorite. Some complain that it's easy to get lost there, I find that being one of it's greatest assets.
It's the most comfortable of all the parks to spend time alone in, so that you can experience things at your own pace. Sure, meet the family for a trip down the rapids, or on the safari, but wandering the trail by ones self can be just as entertaining.
As far as the issue of keeping the park open later (even into the evening) the imagineers were smart as to place Dino-land and the future site of Beastly Kingdom towards the front of the park.
Both lands are to the immediate right and left of the "Oasis"(front gate). The live animal lands (Africa and Asia) are towards the back of the park, so they could be easily closed while keeping Dino, Camp Mickey/Minnie (future Beastly Kingdom) and Discovery Island open for business. Since there was considerable investment in shops and restaurants in these areas, we must assume that Disney management would like to get more hours of operation out of them. I would suspect however that there could never be any type of fireworks for the park as they would definately bother the live beasts. This could lead to a whole new type of night time entertainment experience. Something that's quiet and doesn't include pyro. Are you imagineers up for the challenge?
How do I feel about all the talk of DAK expansion? Well right now Beastly Kingdom is just a bunch of pretty artwork in the Animal Kingdom book tracing the story behind Animal Kingdom. Yes there is a dragon in the logo, so we should assume that SOMEDAY there will be some form of Beastly Kingdom, and I do welcome that day if it comes. Heck, I love a good themed roller coaster and I'm sure Disney could really out do itself on this one, and imagine the possibilities when you throw in unicorns, but the benefits of higher attendance due to a Beastly Kingdom type area would also justify creating more areas like Africa and Asia, maybe Austrailia or South America, or how about both. Then the folks that got dragged to DAK (cause they just don't like searching for adventure) can stay up front at Dino-land, Discovery Island and Beastly Kingdom, while us true Animal Kingdom fans can have the back of the park with a little more breathing room.
One quick note about Mickey's Jammin' Jungle Parade.....I thinks it's truely one of the best daytime parades Disney has produced anywhere. It's simple, and it's got a great beat.
