Hotel 
To dream about hotels refers to a new unusual state of mind or a shift in your usual paradigm. It can be an attempt to break away from your daily routine by going for a lighter, less serious approach to matters at hand.
Casino
To dream that you are at a casino represents the person inside you that readily takes chances. If you are a more restrained individual, this dream could suggest that you need to accept more risks. If you are outgoing, you could be required to make a reasoned decision rather than accepting chance or destiny.
Las Vegas
To dream that you are in Las Vegas signifies luxury and gluttony. You need to show some better control at some aspect in your life, especially those relating to earthly concerns and desires. Alternatively, it suggests that emotional problems and concerns will affect how you perceive things in life.
