I made several room reservations today for a trip I am taking with friends. Tonight, when I went to check on the reservations made (never got any emails), 2 of the rooms have a "free room night voucher" assigned to them, and no price/taxes. I did not ask for this- the reservation agent and I did have a nice rapport, but.....hmm....

so do i call up and inquire? do i leave it alone? will i be asked to produce these vouchers? do these vouchers physically even exist? or will i just be able to check in and that will be that? it happens to be my room and my best friends room who got these assigned to them. all other rooms are correct--price/size/bedding, etc.....

TIA!
