You didn't say when you were planning to go to WDW, but maybe I can make a couple of suggestions to help you make your decision. If you are planning to go this year, call CRO and find out if Annual Pass Holder discounts (code CKN) are available for your travel dates. If so, you may find that at least one AP would would be helpful in obtaining a great rate at a Disney resort. If your trip is eight days or more, you may find APs the best economical choice (unless you plan to visit the water parks a great deal). The most important matter to consider is whether you will be returning within a year. If I had known then what I know now, I would have purchased APs for our first trip. I knew we would be going back, I just didn't know if we would return within a year. Instead we went twice again within that year!! That is a tough call, but you might want to give the matter a bit of consideration.
Good luck!
