As a deluxe resort, the room-only discount at the Poly is likely greater than the room-only discount at CBR, bringing them closer in cost. When pricing it out online and adding tickets, it actually shows you the price for x days and that should remain static regardless of which resort. I'm not sure why adding the tickets to CBR cost more - that actually sounds like one of your settings dropped off. I'd try again and make sure you have all the same settings. And also that it's using the right discount codes, not the S/P/D code.
