Accompanying Guests Accompanying guests are welcome! There will be no official sightseeing programme during the day but accompanying guests are welcome to join the evening functions. There will be a charge of €125.00 (excluding Austrian VAT) to cover the costs of F&B. If you would like to register an accompanying guest, please send an email to Registration. If your accompanying guest is looking for ideas of things to do during the day when the programme is taking place, then please see the "Pre- and Post-Event Ideas" page for some suggestions.
