The Renaissance, a great four star hotel in the centre of Oklahoma City, was the first non-motel accommodation I stopped at whilst driving Route 66.
The combination of great location, friendly, helpful staff, and a beautifully designed atrium made my one night stay a total pleasure. As far as design/style is concerned it couldn't have been in greater contrast to the range of motels I had experienced up to that point. However, the modern design and cosmopolitan vibe didn't prevent it from being both warm and welcoming; the staff at the valet desk were more than happy to offer advice to out-of-towners.
The room itself was fairly standard fair but clean and comfortable, while the breakfast buffet offered a great choice. I'd say the only negative point would be the $20 valet parking (which can actually be avoided by parking in the adjacent and connected Convention Centre).
We spent the night a short walk away in Bricktown where we ate at a great Mexican restaurant called Abuelo's and nursed a few beers whilst watching a live blues band in The Biting Sow - a wonderful evening.
