Cascades Lower has no range, just a putting green. If you want to warm up on a range you have to do it before you leave the hotel a mile or so away.
My understanding, though, is they have purchased adjoining property to build a range. I think the reason was the USGA told them they had to, if they wanted to get top amateur tournaments in the future.
No matter, I'm sure they'll just jack up resort prices to pay for it. "For the good of the game"...
