Las Vegas has a lot of hotel rooms

I always figured that the huge hotels in Las Vegas must mean a lot of rooms total in that city, but I never suspected just how outsized the hotel market is there.

Las Vegas has about 133,000 four or five star quality rooms. How does that compare to other tourist destinations? Paris has about 11,000 such rooms, and London has about 37,000 (despite the fact that London is at least twice the size of Las Vegas).
