Overall, this is a very good hotel to stay at during a Las Vegas trip.
Compared to some other places, you can find some amazing deals here. I've stayed three times and never had a bad time. Staying in the main pyramid is cool since your room wall is set at an angle and makes it a bit different than the typical hotel experience. The rooms are kept very clean and the toiletries are a good, decent quality. On my second trip there, I stayed in a suite that included a Jacuzzi in the room, which was very fun. While this is on one end of the strip and can be a bit inconvenient, it's still a really good choice.
The place is huge inside, like most of the casino hotels/resorts, and it's fairly easy to navigate yourself around.
I tried out the pool and that was pretty nice - huge main pool and a decent Jacuzzi.
While this may not be as glamorous as Wynn or Bellagio, you get great quality at a really good price. If you stay anytime from Sunday through Thursday, the rates are ridiculously good!
