I can assure you that AKL is a destination unto itself. Seems what Eisner refuses to spend on maintaining the parks does not impact what they've done in the area of resort hotels.
AKL is simply amazing. We made a point to visit in 2002, and then made a point to stay in the concierge in 2003. My suggestion would be to make it an afternoon/evening.
Depending on how early you eat, you might make reservations in Boma or elsewhere. Arrive an hour early or so and tour the resort. Try to arrive before dusk so you'll have enough light to appreciate the beauty of the lodge.
If you can spend a night (I'd recommend at least two nights) it's worth it. Keep in mind the busrides are longer and if they've cut back on scheduled transportation it will seem like forever. You can get a good deal with a code now and then.
Either way, enjoy. Also, if you have not checked outthe "Wilderness Lodge", I believe it was designed by the same person and offers just as much in the way of design.
