And THIS is how you use points - for stays at Ibis, Adagio and perhaps Mama Shelters, i.e. the brands where you'd earn poorly per EUR / USD / (insert currency) spent. Spending points on stays at luxury properties is a bit of a waste.

And yes, pretty much all hotels accept payment with points - except for those not participating in ALL outright (the info box on the hotel page will say so), and some prepaid rates where it outright says it's not possible to pay with points (no coin symbol). If the rate is post-paid (settled on location) and the hotel participates in ALL, you will probably be able to settle with points (and cash for the remainder) on location.

That said, Accor's IT is as fickle as it gets, the booking system may fail to show the coins symbol next to a rate that you are perfectly fine paying with points for, and sometimes even if you are logged in, the prompt that lets you use your points won't display on the payment screen (the only solution is to restart the booking process until it does). Finally, with post-paid rates you can sometimes "burn" points when booking (and the points will disappear from your account), but on location you may discover Accor never let the hotel know of it, so some extra mailing and calling (hopefully on the hotel's part) may be necessary. In short - brace yourself, and enjoy the quirky ACCOR experience
