The largest hotel in the world can accomodate over 7,500 guests

The largest hotel in the world is the Izmailovo Hotel in Russia which can accommodate over 7,500 guests. This sounds impressive (or uncomfortable depending on your preference) until you learn that the largest cruise ship constructed, the Symphony of the Seas, can "accommodate" 6,780 passengers and 2,100 crew members. We would rather stay in the hotel.
