I travel a lot and negotiations are expected pretty much every place I've hobbied except here. In many places they will have and show little to no respect for you if you don't negotiate. It's not uncommon to agree to about 25-33 percent off the asking price and then have the best time ever afterwards.
But here in Dallas, I never negotiate. I have a range and I stick to it. I will clarify prices before I book if I see different rates in ads, reviews, showcases and/or on P411. That's pretty much it in the old nut sack.
