I'm not sure that's correct. My understanding was that the certificate had to be redeemed, not just attached (since an attached certificate can be "dis-attached" and moved), and it was "redeemed" at check-in. Thus, check-in had to occur during the validity period, and once you had checked in you were "good" for the whole stay even if check-out was outside the validity period. So, "completed" no, but "started" yes. At least, that's my understanding.
