Seminars and company events
InnStyle is a business event venue on the Maarsseveense Plassen in Maarssen, between Utrecht and Amsterdam. It hosts congresses, trade fairs, product and car presentations, business festivals, company parties, management retreats, hybrid events and team-building days, for groups from a small meeting up to 1,000 guests. The business has organized events for 30 years as a family company and offers a full-service approach: the team plans the day, the technology and the details so the client can focus on the message.
Activities are woven into the program. A brainstorm can continue as a walk by the water, and a presentation can be followed by a challenge. In winter, from December 1 to the end of February, the venue offers three ready-made concepts: a winter package, InnSnow with an après-ski atmosphere and a curling rink, and Sparklinn, a gold-themed evening with a walking dinner.
Rooms and capacities
Two buildings and an outdoor area are available.
Location 1.0 is the largest venue. It covers 1,100 m2, holds up to 1,000 people and has six rooms, including a large plenary room with high ceilings and flexible layouts. It suits conferences, product presentations and large business meetings, and the inside opens toward the water.
Location 2.0 covers 1,000 m2 and holds up to 500 people across nine spaces. Two plenary rooms handle the main sessions, and several break-out rooms serve smaller teams. It is used for conferences, information days, company parties, management retreats and product launches. Large terraces face the water.
The outdoor spaces cover 1,500 m2 of water, beach and grass, used for team building, business festivals and activity programs, with activities such as kayaking. The official site does not give separate capacities for the individual plenary rooms. The ground floor is fully accessible with adapted restrooms, and a quiet room can be reserved in advance for video calls.
Catering
Catering is organized by the venue as part of the event. Client testimonials mention a Mediterranean lunch by the water and a dinner, and the winter concepts include drinks packages, food stands, sharing platters and a four-course walking dinner. Dietary requirements are catered for. Details of menus are on the venue's culinary page rather than in the overview.
History and setting
The venue sits in a hidden location on the Maarsseveense Plassen lakes, with water, greenery and a view across the lakes. The family business behind it has run events for three decades. The site uses energy-efficient installations in the second building.
Getting there
The address is Herenweg 55, 3602 AN Maarssen. The venue is five minutes from the A2 and A27 motorways, close to Utrecht and Amsterdam, with 1,000 free parking spaces. The site mentions roadworks that may cause delays, so check access before the event day.
