Booking Tips for All Venues
- Always book via your Europe DMC partner — they hold pre-negotiated rates and priority hold access
- Request site inspection before confirming — photos never capture acoustic problems or layout limitations
- Ask about parallel events — sharing a venue with another large group impacts service quality significantly
- Confirm in-house vs. preferred external caterers — some venues mandate expensive in-house F&B
