We haven't stayed at AoA, just walked around it one day and ate lunch. It looked fun.
But we've stayed in a regular room at AKL and love that resort. I guess you're looking at 1 bdrm suites? Some people on Dis have had good sucess using David's
DVC to rent points. But only if your dates are 100% sure. Renting points from a DVC owner is different than booking the DVC unit with Wdw as a cash booking. DVC points are non-refundable. Another difference is with renting DVC points, you don't get daily housekeeping as you would booking it as a cash booking with Disney. But renting points can be a big savings.
A big part of a WDW vacation is advance planning. Another good website for planning is Allears.net. Look at the accommodations section, it has fact sheets and photos of each resort, including DVC.
A great planning book is WDW Unofficial Guide. It was my bible for my first few trips. Their touring plans were great, they work, and you'll spend less time on lines and more time doing things! As I mentioned, WDW isn't like a regular vacation, and advance planning is important to a successful trip. The one thing you don't want to do in WDW is wander the parks aimlessly.
Happy planning!
