OK. We are missing some detail, Because I am a professional late booker and the OPs story isn't flying...
Just a few weeks ago I booked two nights in the "dreaded" October window (at BWV no less) It's VERY rare I can't find ANYTHING and as I am still playing with this trip I have checked it a lot lately. While I can't find another BWV Garden View Studio for the nights I want to add I can find other options.... So...
These are my rules for late booking. If you aren't able to play by them then
DVC is going to frustrate you IMHO
1. You MUST be flexible on where you are willing to stay. If you can't be happy at SSR and AKV it's going to be a problem
2. You must be willing to consider moving and/or wasting points. For example I just seached MOST of October because I was very curious about the "it's all sold out assumption above" And it's not! SSR was showing LOTS of nights for a studio and even more nights if you wanted a one bedroom. As a solo late booker, do I need a one bedroom? No, but there are times it's what I take because that's what my options are.
3. You need to use the waitlist. I have a night on Waitlist at BWV. Now if I don't get it, I am staying offsite However, I generally do get what I want especially if I waitlist SSR or AKV. (the reason I didn't bother with them on this was it was a third move for one night when the plane leaves at 7 AM .. the airport may make more sense LOL!)
Of course I think the "pin at 30%" is hysterical. the hotel rooms at Disney are worth about 1/2 of what they charge (less if it's a "Disney Deluxe") and you would be happy with 30% off? I am not. At 50% off they would be close to normal rack rate and I can get discounts off of that at just about every hotel in Orlando so..... I stay offsite if the DVC late booking method lets me down. Lots of good reasonable priced options with more features and benefits then Disney (Sorry, but cute only goes so far!)
Dean thinks I am insane, but I have owned by DVC for 10 plus years. I book exactly ONE reservation a year about 10 months in advance (BCV one week one bedroom for Food and Wine) . Others I have booked as late as "I am at the airport got anyplace I can stay" LOL!
Now if you only want an Epcot resort studio or a BLT etc... then this was a bad choice. Sorry!
