I recently attended a week long conference/group holiday at this venue for around 100 people, organised by volunteers from within the group. These organisers (and all of us) were thoroughly taken for a ride, price-wise. Not only was the accommodation expensive (although this is normal for Sweden) but they charged extra at the last minute for use of otherwise empty rooms, on a hourly basis, and all to be locked at 11pm. They also did not provide tea or coffee between meals. Our organisers were not told of these extra charges and they had not budgeted for them. A few members of staff were lovely, but the management were very difficult and unhelpful. Would definitely NOT recommend as a conference centre.
Perhaps if you go to the campsite and bring everything you need yourself it's OK.
