The resort discount is nowhere near what it is at WDW. I think I only got 30% off when I visited in June. Look on the HUB and it has the number to call. You get free admission with your maingate. If you are just getting yourself in it doesn't count against your normal ammount of guest admissions, but if you are getting people in its like it is at WDW.
You get your normal discounts on merchandise & even get a discount on QSFB!
