Is there a real plenary room with stage, sound and projection?

Absolutely. Our plenary rooms come with a stage, professional sound, 4K projection and microphones, plus a control desk and on-site technical support all day.

Can we alternate plenary, breakout workshops and networking time?

Yes, that's the whole point. You move from the main plenary to breakout workshops in minutes, then to a cocktail or networking time, without ever leaving the venue.

How do catering and breaks work for a large group?

Breakfast, lunch, gourmet breaks and a closing cocktail are crafted by our Chef with local, seasonal produce, and scaled for all your participants. Every diet and allergy is taken into account.

What's included in organising a convention at Comet?

Everything is included: the equipped plenary room, workshop spaces, tech with a control desk, catering from morning to evening, reception and a dedicated contact. One quote, no vendors to coordinate.

Is it simple to organise despite the scale of the event?

Yes. You have a single contact from the first brief to D-Day, a clear all-inclusive quote in under 24h, and a team on-site on the day. Organising a company convention becomes a real pleasure.

Are your venues in the city centre and easy to reach?

Yes. Our convention venues are right in the heart of Paris, Brussels and Madrid, minutes from metro and train stations. Your employees and speakers arrive effortlessly, including from other cities.

How much does organising a company convention cost?

The price depends on the venue, the duration and the number of participants. The quote is all-inclusive, equipped plenary room, tech, catering by the Chef and a dedicated contact, with no hidden costs. It takes just a few minutes for an initial estimate.

Are your venues wheelchair accessible?

Yes. All our venues meet public-venue standards and are fitted for people with reduced mobility: accessible main entrance, adapted reception and access to upper floors.

Can the venue be branded in the company's colors?

Yes. Our spaces lend themselves to your scenography: signage, stage dressing, screens, brand areas. Your dedicated contact coordinates the setup with your teams or your agency.

Can we plan a hybrid format with remote participants?

Yes. Our rooms are equipped for recording and video conferencing: cameras, microphones, 4K projection and fiber Wi-Fi. Your remote participants follow the plenary in good conditions, with our technical support.

How far in advance should you book your convention venue?

For a convention gathering everyone, it's best to book several weeks ahead to have the pick of venues. Once the date is set, your dedicated contact orchestrates everything else.

Can a convention serve as an annual kick-off?

It's a common use: a launch plenary with management, team workshops to cascade the objectives, then an evening to celebrate, all in the same venue.

What about a client event or client evening?

To host your clients, the best format is often an evening: a short speech, a cocktail by our Chef and real time to talk. See our guide on organising a networking event.

My quote in 2 minutes

Company convention: how to organise it, from plenary to evening

A common thread for the whole day

A company convention often brings the whole company together around a direction: the year's results, strategy, the launch of a project. Choose one main message and build the programme around it: plenary in the morning, workshops in the afternoon, a highlight at the end of the day. A back-to-work kick-off follows the same pattern, over half a day or a full day.

A real plenary room and rooms for workshops

The venue must hold everyone in plenary, then offer nearby rooms for breakout groups. Comet Arboretum hosts up to 400 people in La Plénière, Comet Bourse La Ville Rêvée up to 280 people in its Auditorium, and Comet Bercy up to 200 people in its Plaza.

AV and stage management

Sound, projection, microphones, filming or streaming for remote teams: every detail counts when the whole company is watching the stage. At Comet, AV and an on-site technician are part of the quote.

Catering for a large group

Breakfast, lunch, breaks and the closing cocktail are prepared by La Table du Chef Meliava with seasonal produce, and sized for all participants. Every dietary requirement is taken into account.

Extending into the evening

A convention often ends with a cocktail or an evening event on site. Teams stay together, with no transfer to a second venue.
