First inaugurated in 1968, the big-top action at this family-friendly hotel is billed as the largest permanent circus in the world. High-wire, trapeze, juggling, acrobatics, and more fill the top of the “tent” daily from 11am until late at night, while more than 200 carnival-style midway games get the young ones inured to the joys (and heartache) of risking money for questionable odds of a reward. Note that while the attractions here are definitely kid-friendly, you have to go through the casino to get to them.
