If you are staying onsite, they will print out a copy of your ADR's at check in. I have all my ADR's confirmation numbers written down, but Im going to have them print it out when I check in at CBR next month. You could call and verify your ADR's also. Hope this helps!
Heck Yah!!! Just call DW dining -- I always call and confirm before I leave...I don't like to deal with last minute surprises while I'm already there. You don't even need your reserv. numbers. Just give your name and telephone number you gave when making your ADR and the CM will tell you all your ADR times and place. I even call and confirm my DW hotel reserv. before I leave.
