Size - what are the dimensions of the smallest space - taking into account recesses, alcoves, protrusions, wall lights, wall mounted screens, radiators, kitchen access and fire exits which must remain clear. We always take our own measurements using a laser measure.
Capacity - what is the seating style for the event? Dinner, cabaret, theatre, boardroom, reception or something different. How much equipment or dressing will be needed that will take up space - will there be rear-projection AV?
As a quick guide, in theatre style seating an average conference chair size works out at 20 people per 10 metres (without aisles). In dinner or cabaret seating - one 6 foot (72cm) round table seats 10-12 for dinner and 7-8 for cabaret - with chairs it takes up a 10 x 10 foot space (3.5 x 3.5m). At a reception, each person takes up 1 metre square.
Ceiling Height - The minimum height taking into account alcoves, chandeliers, lights, permanent fixings (like mirror balls or projectors) - the minimum base of a projection screen has to be 1.4m from the floor which means you need at least 3 metres total height. The lower the ceiling, the more oppressive the room, particularly in long meetings.
Floorplans - Does the venue have them and more importantly are they accurate? More than once we have received inaccurate floor plans, leading to a lot of tight spaces on the day. That's why we measure! Ideally the venue will have CAD plans that we can work with.
Noise - does the room have moveable dividing walls? What is happening on the other side of them (no temporary wall is ever sound proof. Where are the kitchens, will the noise carry? Is there a lot of echo in the room - when you clap your hands do you hear one or more claps? Are there soft furnishings and carpet to absorb sound? Is there any construction work outside or nearby railway lines, or an active airport next door or a scheduled firework display (we have been affected by all these things).
Light - is there natural daylight? Are there curtains or blinds if darkness is needed? What type of lighting is there and how is it controlled?
Catering Space - is there a dedicated catering space separate from the meeting rooms? Will the catering space share space with displays or registration? Will catering be in the meeting room itself? Where are the kitchens and will kitchen noise before or after the food affect the meeting. What is the access like for catering staff - this can affect what you do and could slow down service.
Catering
This is one for a separate post! At the recce, we are interested in where the catering will be provided, Depending on the event, we are interested in: Breakfast (few hotels can cater for all of their bedrooms in one sitting but with a fixed start time, you may put more demand than they can cope with).
Breaks. Where? What (coffee, tea, juice, water, biscuits, pastries, fruit)? How frequently.
Lunch. Where? In a shared restaurant? Buffet (how many stations, how will they be laid out?), seated?
Dinner. How many wait staff, do they have dedicated drinks staff, how will the bar operate (where is it) - there are lots of questions for dinners.
Menus. What are the standard menus like, how imaginative and how prepared are the kitchen to accommodation something different?
Dietary. Plan for them! Lifestyle (vegetarian, vegan), Religious (Kosher, Halal), Medical (nut, dairy, shellfish, wheat, gluten etc.).
