Well, you know how much I love CSR, and I know how much YOU love CSR. I'm not sure it would be a Disney trip for you if you weren't hanging in your hammock. But I also know how much you want to stay at AKL and can totally relate - we are booked for four nights at AKL in January.
I voted for option three - I think it will be hard for you to be at Disney and not be at CSR. But AKL is truly a unique experience at WDW, and I'm looking forward to trying it in January. CSR will probably always be our first choice, but change is good sometimes.
If your dates are flexible (not sure if you have to have three days before and three after), how about two days at AKL either before or after Marco as resort days, while you do the parks with four days at CSR? My only concern about our trip in January (besides that the pool is closed

) is that we won't have enough time to really enjoy AKL since we will be trying to fit so much into 3 1/2 days in the parks. I'd love to hear the storytelling, relax around the pool (if it were open), and sit outside and watch the animals for a while, rather than just checking them off an internal list. AKL seems to be the kind of resort that lends itself to hanging out there rather than running for a bus (not that CSR isn't as well, but you have probably uncovered most of its hidden treasures by now). It's full of places to curl up and look out the window or sit outside and enjoy the atmosphere.
I'll give you the unbiased report when we get back from our January trip. But I can't imagine you being at Disney and NOT being at CSR for at least a few days.
