$100 card hold for DVC stay?

Just new to you. 

It was introduced several years ago, pre-Covid, to stop people running up their room charges and then the card being declined.

It applies across all resorts. Once you run up $100 on room charges they put another hold on the card. 
You can stop that by paying down the charges when you are near to that amount. 

Be aware the $100 holds they put on take a few days to drop off. Pre-Covid we had an incident where all our charges plus multiple $100 holds were on our credit cards plus a glitch on Disneys side that had doubled all our charges and $100 holds. Needless to say having a card charged 4 times the actual amount spent did not sit right with my DH and I as we were 6 weeks from closing on our new house. When we spoke to a CM at the front desk the day before check out about correcting the issue his response to tell us that it should be corrected within 7-10 business days. I asked what if they pulled our credit again and saw this massive charge? We were there for two weeks and use to charge everything back to our Magic Bands. He just shrugged. When I asked what would I do if it maxed out my credit card and I couldn’t purchase food for the last two days of my trip he suggested DH and I get an American Express card since they do not have a limit.

It was so frustrating I wrote an email to the hotel manager while in the airport two days later and got a lengthy apology back. This past June was the first time I went back to that resort as it really soured our feelings after how the CM was. I get it if you can’t do anything about it but your lack of care for my families situation and your suggestion to get an AmEx card was condescending. Clearly all these years later it still rubs me wrong.

We've had this as well. WHen we exceed $100, they add another hold. Very standard for hotels, rental cars. Never a problem, and never materializes as a real charge unless we actually charge something.

Cheers.

When we have checked in online we have had to put a credit card on file. When we have done that we have gotten the $100 charge/hold on our card but for numerous days. They keep adding the charge daily even though we don't charge anything to the room. It doesn't really affect us but I find it annoying.

I am feeling kind of dumb because I never realized this was happening.  We always put a card on file during online check in and we charge on the magic bands.  Haven’t had any kind of issue so far and I don’t check on my card balance during a trip. Of course I look at the itemized bill when we get it but have not seen the 100$ hold.  Ignorance is bliss I guess.  

This is pretty much our situation, too: Two week trip, charge everything to the bands, it gets paid automatically and I don't even notice. Ignorance is bliss like you said.

I do remember when they started doing this, though, I remember a huge discussion about it on the group and I think Dirk was very upset about it, maybe I'm wrong about that. But it never caused me any issue.
