Fish2girls, we stayed at the Poly for the first time this past Feb. (first week) Third floor Samoa, vol. pool view, and I loved it! Thought we'd been upgraded to lagoon view when I stood on the balcony! My TA helped me request a good room since I'd never been, and she was right on...
We never felt we had to walk so far, and never were bothered by a lot of noise. Keep in mind, however, that we went the first week of Feb. so the pool is not exactly full!!!
As for discounts, the only one I knew about at the time was
AAA, and it saved me 15% off the rack rate at the Poly. With their rates, anything helps!!
