I have done this with them - generally for a few that I could not find my conf number for. I am sure they will do the whole time for you. You can also ask at checkin and they can print them all off. The only problem I have is sometimes not thinking I will make the reservations using different phone numbers. Usually I give my home phone number but if I give my cell then they will not be listed. If you think you gave more then one number you need to check both numers.
