We did a grand gathering at Poly in June. We had 3 rooms booked under my military discount. You have to call to book, can't do it on-line. All the rooms were paid for separately, using different credit cards, under different names, but linked together in the computer system for the discount. I drove with my kids, my mother, sister, and sister's family flew. I happened to arrive first and checked into one room. I was never asked for ID, they didn't even look at the reservation, other then to see how many people were going into the first room (to many kids for one room, I had to put 2 in the other rooms). When the rest of the party arrived I did not have to meet them at the desk. They were never asked for any information either, other then verifying who was in each room. This was our 3rd trip in 3 years, all with the military discount, and the cm's have never asked for military ID. One trip my mother and sister arrived before I did and were still able to check in without issue.
