Coolest hotel?

The absolute coolest hotel I ever stayed in was the Mirage in Las Vegas, NV.  Besides it's tiger habitat and having the best pool area out of all the Vegas hotels, I was fascinated by all the colors inside, the courtyards with trees, the huge aquariums, and the Beatles show that was appearing there at that time.  There was a walkway leading to it that changed different shades of the rainbow constantly.  Nevermind all the hustle and bustle and there being always something to do and people to watch, our room was upgraded to the top of the building and it's the most posh setting I've stayed in to date.  I'm talking a flatscreen, purple leather headboards, frosted countertops, geometric rug and bedspread patterns, and curvy lines.  A view down the Strip was seen out the window, and I never wanted to leave.
