Do you think you'd spend a lot of time in a 4 day trip appreciating the amenities of your resort or would you be dawn to dusk park commandos?
Would you have access to your own car or would you be reliant on Disney buses?
Is your party big enough that a third bathroom would make a big difference? Or are you a smaller party that prefers more space?
Animal Kingdom Villas are truly unique and worthy of anyone's time...if they make the time. If you know you'll spend at least 1 day hanging at the hotel, or if you have at least one member of your party who couldn't really care less about going to the parks and would rather explore the hotel, then Kidani in a heartbeat. But if you plan to hit parks from open to close every day and the hotel is just the place you plan to shower shave and sleep, maybe it's better to save your money.
We've got a split stay coming up - 4 nights at Kidani, 5 at Bay Lake. Check in day, most of our second full day on property, and least the beginning of our check out day is just about being at Kidani.
