Well, for me its not worth it. I just had this same dilemma myself, then waited too long and could only get All Star Music lol! But I came to the decsion that if it was $600 more to stay at the Poly or CR over CBR then I would go with that. But the WL rooms are not that much if any bigger than CBR's and I love the tropical theming of CBR. We had nine wonderful nights there and its my favorite resort outside my DVC. To me its a theming thing, I live in Colorado, so that northwest woods theme feels too much like home! You can't make a wrong choice, the WL is lovely, close to the MK and I rarely hear anything but happy reviews of it. But CBR was wonderful and to me $600 is still $600 for rooms that aren't that much bigger. They do have queen beds and a balcony however, so if those are things that really matter to you then that $600 would be well spent. We are short so doubles are fine and the balcony thing isn't worth that much more for me. Good luck with your choice!
