You can find cheaper places in Vegas... if that's what you need. If you want something more memorable I would recommend this place. The background is what you expect (a lake), but not how you expect (scenically beautiful beyond expectation). If you're unsure about this place, before you decide against it check it out in person... the pictures cannot compare. Wynndy helped us and she was (as my now wife said) "super amazing". I would add very helpful and accommodating.
