In addition, we ask that you tentatively let us know your arrival and departure dates, so that we can plan for the appropriate number of attendees on each day of the conference.

Step 3: Completion of registration. After you have paid the registration fee and completed the survey, we will contact you to confirm your registration. Please note that this e-mail will not be sent automatically, and it may take a few days to receive the confirmation.
