I will try to persuade you: We spent DH's 50th at AKL and loved it. Great theming, great food, savannah view rooms, gorgeous lobby and the amazing savannah. Honestly, we have stayed at both Poly and AKL twice and prefer AKL. We love the savannah and usually visit AKL for a visit to the animals and a meal at Boma or Jiko, even on trips when we are staying at a different resort. We love sitting around the AKL firepit in rocking chairs at night, too. Let's not forget the tasty zebra dome cakes at Boma. If the difference between the Poly and AKL is $600, I would definitely stay at AKL, especially if there is construction at the Poly. (On our last two stay at the GF, there was a lot of construction and it did take away for the charm.)Also, you could take a portion of the $600 savings and put it towards a car rental. If you research, you can get some good deals and then you won't worry about transportation. We always rent a car no matter where we stay, but when we have taken the bus from AKL, it wasn't bad at all. Hope this helps.
