We have been alerted to the fact that companies going by the names EHS Exhibitor Housing Services and EHM Exhibitor Housing Management are making telephone calls to conference participants. They are claiming that they are “from the congress organizers” and that they have a special hotel deal or that something is wrong with your hotel booking for EGU2017. Please ignore these calls (and/or emails) and do not provide them with your credit card details. Mondial Congress & Events is the only official housing agency for EGU2017. If you are unsure about the status of your booking, please contact Mondial.

Please note that the congress ECCIMD2017 with 10,000 participants takes place in Vienna in parallel to the EGU2017. In addition, the Vienna marathon with 40,000 participants takes place on Sunday with load on the hotels in the night before. Therefore, we strongly advise all conference participants to reserve their hotel accommodation as soon as possible. Mondial Congress & Events will not be able to guarantee rooms after 24 March 2017.
