I've stayed at AKL a few times, always in a savannah room. This past trip, I got a great rate for a standard room, but it was over $100 more per night for savannah so I booked the standard. I'd read a lot on these boards about people getting free upgrades from standard to savannah so I just hoped for the best and figured I was happy enough with my rate that it didn't really matter. When I got there, I asked about an upgrade and was told $60 per night for savannah and $10 per night for pool. I figured $60 was better than $100 per night for savannah, but still more than I wanted to spend. I ended up paying for the upgrade to pool and was glad I did.
