We are on the dining plan, I did an online reservation. It didn't ask for any reservation number or anything. Is this weird? Will we still be Ok to just show up for our reservation and tell them we are on DDP?
Yes you will be fine. When you make ADRs online there is a place that asks if you want to associate your ressies with the ADRs. You click on that if you do. It's really only needed if you want to do all 10 days at once.
