All nights must be prepaid in advance. The amount corresponding to your entire stay will be charged upon reservation and will be automatically deducted from the total amount of your hotel bill at check out. If you shorten your stay, no refund will be made of the cancelled pre-paid room nights. In case of no-show, no refund will be issued. Bookings are ensured on a first-come first-served basis. Payment of the reservation fees is to be made in EUROS (€) only.
Upon receipt of your hotel reservation request, Congress Secretariat will send you an invoice/confirmation letter summarizing accommodation details and specifying your payment status.
