The "Saved Offer (PIN code) trick" I discovered (and I am taking credit for discovering it, as I never saw anyone mention it on the DIS before I stumbled upon it last year!

) has worked very well for some of us. I have received 2 PIN codes in less than a year by doing this same trick twice.
Both of my PIN codes were good for only one-night stays or more - they did
not have a 2-night minimum. So if you get one like what I got, you will most likely get one of the ones that is good for one night.
This is exactly what I did, both times:
1. First, you have to make sure to create a "
My Disneyland" account on the Disneyland website. Specifically go to the actual Disneyland Resort website (as opposed to Disney.com) and look for the icon in the upper right quadrant of the page that says "
My Disneyland."
2. After you have created your My Disneyland account, fill out all the standard info and answer the questions they ask you (do you want to receive newsletters and offers, etc.), as that will assist in possibly getting future PIN's.
3. Stay signed in to your My Disneyland account. Then, pull up the hotel section and plug in the dates of your trip at the hotel of your choice (example, September 6th at Paradise Pier). The DLR website will price it for you and show you the "offer."
4. Somewhere at the bottom of the offer will be a tab to "Save" it. Click on "Save Offer" or "Save" or whatever it's called, and it will automatically save to your My Disneyland account. In fact, you can double check your My Disneyland account to be sure it's there.
5. Then sign out. Don't buy anything. Don't book anything. Don't put any money down.
This will send a message of sorts to Disney Destinations, alerting them that a potential guest was pricing the hotels and showing interest in staying onsite by saving an offer. They will see that you did not book the hotel yet, so they will most likely send you out an offer with a PIN code (that is especially for you) that is better, such as Paradise Pier Hotel for $156 per night or $163 per night, etc.
You may get this offer in a few days or in a couple of weeks, and it may arrive via e-mail (with a subject line about Photos of the Resort you chose) or via snail mail.
Many people have had luck with this PIN code trick when they followed my step-by-step instructions, especially at first. After a while, I think so many people attempted to get PIN codes that Disney Destinations stopped sending them (they probably ran out of rooms attached to the PIN offer), or they began sending 'alternate' PIN's for Disney World. I think the current wave of PIN's have "claim by" dates on them, and when they are not used, that will free up more PIN codes in the system.
Also, they may send you a PIN code that does not cover the dates of your trip - that has been happening too. So be forewarned that the trick may work like magic, or it may not work at all!
