I'll try to help a little more. Disney advertises their codes through newspaper travel sections and postcards to previous guests. They are usually three letters, i.e. "XYZ" code. When people see them they share the info with others here on the disboards and on
www.mousesavers.com. What mousesavers does is to put lists together to make is easier to see what is our there.
AP means Annual Pass. It allows you into the four parks as often as you want for a year. Disney often times offers a discount on rooms for AP holders. An annual pass costs more than a Park Hopper Pass, but the savings on a room has always made up for the cost of the AP. If an AP discount (code) is offered only one person in your party needs to hold an AP pass and you do not have to have it to make the reservation. You only need it at check in. Therefore, you do not have to purchase the pass unless it is really going to benefit you.
Back to mousesavers: check out the web sight. It will tell you everything. Some of the different type of discounts you will see are: Annual Pass, Postcard or newspaper codes (and whether these are for everyone or not), discounts for residents of certain states, military discounts, etc.
As far as your Poly reservation, a lagoon view room at the Poly with concierge service is $470.00 a night when you want to go, an Ultimate Park Hopper pass (which comes with the package is $365.30. I think that calculates to $5129.55 for four of you if you were paying full price. Please don't take my calculations as gospel! You can check room rate for yourself at disneyworld.com and ticket prices on the disboards under Theme Parks. A garden view room without concierge is $299.00, something to consider.
This is a hugh amount of information, probably more than you needed! Hope it helps a little. The more you check out for yourself the easier it is to understand.
Good Luck and have fun planning!
