That is odd. But that thought did cross my mind earlier in the week.
We are splitting our stay between WL (cash) and BCV (points) and when I called the other night to add a night to the front of our trip the CM asked how we were getting to WDW. When I told her we were flying in she offered to make DME arrangements for us. Even though we are staying on points for the last part she made all the arrangements (I hope!). I wondered at the time how she was doing that since she couldn’t see our DVC reservation, she just took my word for it.
She told me I wouldn’t get anything about my DME arrangements until about 20 days before my trip. That’s a long time to wait to make sure everything is fine. I may have to call and double check this.
