As someone who tracks:
- Rack rate
- Best public discount rate (Disney+ sub counts as public, IMO)
- AP discount rate
For 14 room types ranging from Pop Century to Bungalow + the Same Room As Booked for every single stay, I gotta say I'm often underwhelmed with the discounts. Discounts of 25-35% often get the headlines, but they're not universal and often fill gaps that don't make sense for us.
For Same Room As Booked, the average public discount offered/published is just 4.8%. Average AP Discount is 6.8%. And this is before considering whether there's any available inventory to book, I record the discounted rate even if it's offered but 'sold out' (or never actually available). Apparently I travel in rooms that aren't included in discounts or at non-discount times of year.
The best discounted room I've tracked over the years is Yacht Club Garden/Resort View room, with 9.2% average public discount and 14.6% average AP discount. Again, this is before actual availability, just what is offered/published.
As for breakeven, I kinda use them all? It's fun to think how much $$$ we'd have spent staying in nothing but Bungalows ($860k) and good perspective to have that we'd have spent just $51k stay at Pop on AP discount, much less than we've put into DVC.
