Looking to book using Chase Free Night and/or Points for 3 nights in late August and the rewards option is showing non-refundable and deposit required. It does not however list a deposit amount/method it all during the booking process. What do they mean by the deposit- just the points? What happens if I book and then cancel- will they charge me the almost 1,000 Euros per night? Is that perhaps the deposit then? No information is listed and IHG member services is unsure of how it works too, so I'm a little hesitant with booking the reward nights so far.

Any tips/feedback would be gladly appreciated.
