Just a nit pick: I believe you can do the Wildlife Discovery Excursion, which is what I think you mean by Sunset Safari, if you book concierge level at any of the Disney resorts, not just AKL.
It may have been expanded, but when I did it, my understanding was that it was exclusive to the Lodge.
Concierge guests at Animal Kingdom Lodge can sign up for a very special evening called the Sunset or "Wanyama" Safari. Up to 8 people can ride in specially designed vans around the lodge's savannas! The van stops and you get lots of photo opportunities of the animals and birds. An Animal Kingdom Lodge animal guide is on the van with you to offer information and answer questions.
Afterwards, you have a wonderful dining experience at Jiko.
Guests must be 8 years of age or older.
The price for the experience is $150 per adult (ages 10 and up); $75 per child ages 8-9, tax and gratuity included.
Hours: Mondays, Wednesday and Fridays about 1 1/2 hours before sunset at the lodge's Porte Cochere.
