Castanea Resort hosts conferences, seminars, product presentations, company parties and weddings for up to 400 guests. It has 13 meeting and group rooms in the hotel, which together take up to 280 people, and a separate conference building, the Castanea Forum, with more than 900 m² of space. The resort lies on a golf course in Adendorf, in Lower Saxony, and presents itself as just outside the gates of Hamburg.
Seminars and company events
Every meeting room in the hotel has daylight, and some open onto a terrace. The smallest are four rooms of 27 m² named after golf scores, Albatros, Birdie, Bogey and Par, each for 15 people in parliament style, which work well as breakout rooms. The largest is the Großer Saal of 345 m², which seats 300 in rows or 200 at round tables. The Forum adds column-free halls with a ceiling height of 4.90 m, fixed sound and digital signage, individual air conditioning, electric blackout, and a vehicle access straight into the hall, useful for car presentations or large stage sets. Its foyer of about 250 m² has a bar counter and a welcome desk, and a large terrace looks over the golf course. The resort sells day conference packages and supporting programs for team events, and more than 300 free parking spaces serve the Forum.
Weddings and receptions
The resort organizes weddings for up to 400 guests, using the foyer, the terrace and a dance floor. Non-civil ceremonies take place in the farm garden, set with white chairs for the couple, benches with white covers, a microphone and a lectern. In bad weather the ceremony moves to the covered and heated Castanea Lounge terrace. The team can recommend celebrants, musicians and photographers. Birthdays, anniversaries and school graduation balls are also hosted.
