Mauld: Actually the Four Seasons is great, and is one of the least expensive in the Four Seasons chain, and definitely worth the stay. It is one of the more expensive rooms by LV standard. I paid $199 for the night.
Bluebonnet: Your first trip to Las Vegas would be incomplete without a trip to Hoover Dam. It is truly a modern day miracle. I've been to it twice. While I didn't visit Hoover Dam, I was on Lake Mead two weeks ago. Where I was on the Lake, it was a two hour boat ride to Hoover Dam. That shows you it is holding back a lot of water!
