Saving Money on Tickets for Walt Disney World

I am trying to figure out the best way for my family to enjoy Disney World's parks spending the least amount of money. Since we live in Atlanta it really isn't hard for us to get down to Orlando.

Also we usually spend about 5 nights in WDW and then head to one of the Disney Vacation Club resorts on the coast, Disney’s Hilton Head Island Resort or Disney’s Vero Beach Resort, for the remainder of the week, 3 nights usually. Therefore we really only need, max, 5 days worth of the parks depending on what we do the day we arrive and the day we leave.

Our next trip is planned for May 22 - May 31. We will be staying May 22 at the Holiday Inn & Suites Ocala Conference Center Hotel. This is a wonderful property, I definitely recommend it. We arrive in WDW on May 23rd and will check out May 28th. We are staying in the new Animal Kingdom Villa's Kidani Village. Then we will head to Disney's Hilton Head Island Resort for May 28 - May 31.

As Disney Vacation Club members we get a discount on Annual Passes to the Disney Resorts. I have put together a spreadsheet that details the costs. You can see it here. Also, here's an image capture of it:

The "Per Year" line is calculated with the assumption that we would be buying an annual pass only every other year and staggering our vacations so that we can use them on the vacation when we buy them and the next one. We only take one a year, usually, so this would work out pretty well.
