We did that in Feb and got a great deal at CBR. There is a special number that you have to call they call it interline reservations. When you call into the main number, just ask for the phone # to interline reservations....otherwise they will act like they have no clue what you are talking about.
My dad is an AA retiree and they were traveling with us so Disney allowed them to book 2 rooms with the airline discount. It is usually about 40% off of the normal rate. I think we got CBR for about $80/night, which was awesome!
When you make the res you will be asked for a $200 deposit balance due 45 days before arrival. Just like any Disney res. Then they will ask for a faxed copy of your airline employee ID
which will also need to be presented when you check in.
We had no issues at check in or otherwise.
Mom and Dad are going with us in July however, only for 3 out of our 7 nights so I just booked the 4/3 deal this time, which was still a great price.
If you can take advantage of the airline rate, do it! Its a great way to be able to stay at a higher end resort at a low cost.
As far as the tickets, the interline res does not come with tickets so you can purchase them separately....either locally or online. We bought ours at our nearby
Disney store.
Have fun!
