Out-of-state AP here. I do not own DVC nor do I have children. My sister, also an AP holder, and I usually do two WDW trips a year. We did zero trips in 2020 and are hoping to do 2 this year, including the May trip we already did.
We hardly used our last APs before we renewed them, so WDW definitely made money on us there.
But we both did renew, and there's still a 15% discount for renewing an AP. If WDW really wanted to get rid of AP holders, they'd stop offering a renewal discount or they'd stop offering APs altogether.
WDW must like repeat visitors. I say this because they continue to sell DVC, creating an entire group of repeat visitors.
