Hyatt usually places a credit card hold for the entire room rate at check-in. The hold is padded by an additional amount to cover "incidentals".
In the USA, typically HP holds $30 per stay and HR holds $75 per stay for incidentals. This can vary. HR MSP Bloomington holds $125 per stay, which is sometimes more than the room costs.
My main gripe about credit card holds is that they go on within nanoseconds but they go off after several days.

Thus you need enough credit to pay for the room More Than Twice. Consider a one-night stay at $150 For a couple of days after checkout, your credit limit is hit for:
- The expected room rate (held at checkin)
- The "incidentals" (also held at checkin) ... which can be more than the room rate
- The actual hotel bill (charged at checkout)
This post is not about money! It's about the fact that I agreed to pay Hyatt for a room, yet for a few days after checkout I'm actually hit for the room THREE times. In my own business, I'd never get away with charging a customer three times. Why should Hyatt charge me three times?
IME there are many hotel chains which do NOT place credit card holds.
I was pleasantly surprised during a recent stay at HP London Heathrow Hayes. They did not place ANY credit hold at checkin. They didn't even want to see the card at checkin. They simply charged the final bill to the credit card, after checkout. Why can't other Hyatt properties do this?
