I've used hotwire/priceline, and for those services booking a prepaid room, the charge hits my credit card immediately

I booked 2 nights via "prepaid" pricing in a Hyatt for Memorial Day weekend about 4-5 weeks ago, and no charge has been made yet. The reservation is shown in my GP account.

Is this typically how Hyatt does "prepaid" ? That I'll be charged upon checkout ?
