@MikeRigsby: You won't get charged or therefore get a receipt until you check out.  I don't work in accounting so I might not get it all but there is nothing for them to track yet.  You might have used their card to hold the room but it won't affect them until you check in, they'll get a hit to make sure you have necessary funds and it will place a hold.  That hold won't be an actual charge until you check out.  At least thats how I've gathered it works from the acct aspect.  I've had a ton of issues the past few years and have dealt with the acct. dept. a lot as far as how my corporate card worked when attending a conference.
