Mistakes 1 to 3: The Selection Phase
📊 Critical stat
According to an event organiser survey (Event Manager Blog, 2025), 58 % of seminar problems originate in a poor venue choice — and 72 % could have been avoided with a prior site visit.
❌ Mistake 1: Choosing from photos without a site visit
Professional venue photos always flatter reality. A room that looks spacious may be stifling with 40 people. The absolute rule: visit or have someone visit before signing.
❌ Mistake 2: Underestimating real capacity
Official room capacity is given in theatre configuration without furniture. In working configuration with round tables, plan for 30–40 % fewer seats. A group of 50 needs a room rated for "70 theatre".
❌ Mistake 3: Ignoring transport logistics
A beautiful venue 1 hour from the nearest station can become a logistical nightmare. Test the route from your delegates’ main cities before confirming.
Mistakes 4 to 6: The Contracting Phase
❌ Mistake 4: Not reading cancellation terms
Venue cancellation terms can be very strict (50–100 % if cancelled within 30 days). Read the T&Cs carefully and negotiate more flexible terms before signing — never after.
❌ Mistake 5: Forgetting Wi-Fi in negotiations
"Included" Wi-Fi at hotels is often undersized for groups. Ask: "What is the dedicated bandwidth for our group?" and have it included in the contract.
❌ Mistake 6: Underestimating hidden costs
Parking, additional AV equipment, overtime room charges, service charges on catering — extras can represent 20–40 % of the initial quote. Request an all-inclusive quote and an exhaustive list of possible supplements.
The Checklist of Questions to Ask Before Signing

- 📶 Connectivity — Dedicated group Wi-Fi bandwidth? Room with best mobile signal?
- 🍽️ Catering — Vegan/halal/allergy options? Tied caterer or free choice? Service charges?
- 🔇 Acoustics — Soundproofing of breakout rooms? Expected noisy neighbours?
- 🌡️ Comfort — Independent air conditioning and heating per room? Air quality?
- ♿ Accessibility — Wheelchair: lifts, toilets, access to terraces and outdoor spaces?
- ⚠️ Cancellation — Precise conditions per time bracket? Force majeure included?
- 🅿️ Parking — Free, paid, capacity for the group?
- 🔊 AV — Equipment included? Technician on-site or on-call?
❓ Frequently Asked Questions
How many venues should you visit before choosing?
Ideally 2–3 finalist venues for a physical visit. For groups over 100 people or budgets over £50,000, never skip the site visit.
Can you negotiate the price of a seminar venue?
Yes, and it is often very productive. Negotiable elements: room rate, inclusions (parking, AV, coffee break), cancellation terms, rescheduling option. Main lever: show competing quotes and be transparent.
How do you protect against unpleasant surprises on the day?
A detailed written briefing sent to the venue manager 7 days before the event, confirming every point of the contract. And designate a venue contact reachable around the clock during the seminar.
