Just want to post my experience since this thread helped me prepare. We checked in to Pop Friday 4/26 for one night only. Did online check in, never received a $100 authorization on Friday. Saturday morning $100 authorization from Pop hit. No problem since we were moving to BWV that morning. Checked in at BWV and just like Angi, said no cc info on file; which was strange since Pop had just preauthorized my Discover card. Anyway, I gave them the Discover and immediately another $100 authorization. So I haven’t charged anything yet and $200 is tied up in authorizations on my card. No biggie. To avoid confusion, we just used gift cards all day Saturday to pay as we went. Sunday, Pop posted $100 credit to my card so all was clear from that stay. We had brunch at California Grill Sunday and charged back to the room the total (around $190), plus charged some purchases to the room. As soon as we charged California Grill, my Discover card was preauthorized for $212.69; the total of my purchases that day. I paid the balance with my gift card that night and have continued to do so nightly. The total Disney has tied up in pending charges on my card is $312.69 and I just make sure my balance doesn’t go that high. We are charging to the room all purchases and even though some have exceeded $100, nothing more has been preauthorized. I believe if I let my balance go above the $312.69, only then will I get hit with another preauthorization. Hope this helps!
