Hotel Booking:

Some websites or other providers may appear to be offering rooms at the congress hotel at slightly lower rates. Delegates are advised to exercise caution since often these rates do not include breakfast, have to be paid in advance and, in the event of a cancellation offer no refunds. It is also likely that any rooms offered in this way will be of a lower grade than those offered under the EFCLIN booking arrangement.
