We paid around $220/night at the Mandarin. I hesitate to compare it to other places around since I've only stayed in a handful of hotels on the strip. My sister recently stayed at the Aria (right next door for $200/night) and Paris for about $120/night. Neither of these places have a similar calming escape feel to them as they have casinos inside. The Wynn is another comparison I am familiar with (due to its smoke-free environment, modern vibe/decor, and amazing spa). The prices there are comparable.
