Having a Ball (challenge)

Having a Ball is a challenge $$

Challenge requirements
The Courier must go to the bell tower and complete the quest Trigger the Gala Event that opens the gates to the Sierra Madre Hotel.

Walkthrough
After finding all three companions, return them to the central fountain. Elijah will tell the Courier the only way to open and enter the Sierra Madre Casino is to activate the Gala event. This requires the player character to complete three quests: Fires in the Sky, Strike Up the Band, and Mixed Signals (these can be completed in any order). Each quest leaves a companion at a specific point around the Villa. Once all three quests have been completed, the quest "Trigger the Gala Event" starts. For this, one just has to activate the Gala event via a console within the bell tower.
