Generally, Topgolf’s official policy treats vaping the same as smoking. Inside the building (hitting bays, restaurants, and other indoor areas) it is not permitted. Most locations have designated outdoor smoking areas where vaping is usually allowed.
Because local laws and venue policies can differ, it’s safest to:
Ask a staff member at the front desk or your bay host when you arrive.
Look for posted signs or designated areas outside.
If you’re unsure, stepping outside to a clearly marked smoking/vaping area is the safest bet.
