DH and I have officially given up trying to get the 20%, 30%, 40% PIN code. Nothing has worked for us. We've ordered maps and the DVD. We've saved several vacation packages on the account (after clearning cookies). We've chatted with a live person on the website. We've nagivated the entire website forwards and backwards. It seems we aren't destined to get the
one and only PIN offer out there so far, that would make it feasible for us to travel to the World in 2010.
We know there might be other offers down the line, but for us the urgency for receiving a PIN now is simple. If are to travel to FL next year, we need to make sure to snag some decent air fares now. The air fare for our dates will be released very soon. DH told me that if we don't book the resort stay/tickets/dining, etc. with a decent discount now, then we shouldn't book air fare.

So that basically seals the deal. In my experience air fares go nothing but up as it gets closer to the travel date. Therefore, no WDW for us in 2010.
We wish other posters here the best of luck getting whatever PIN will work for them. Hopefully there is more pixie dust blowing in your direction than it has in ours. Here's wishing you the best.
