The official registration and housing bureau for the PRES 2026 Congress is MCI Suisse SA and you should only trust information from legitimate sources like the PRES website, congress website, and MCI website. 

It is important to be aware that you may be contacted by phone or e-mail, or see advertising, by unauthorised individuals or companies that act as travel agencies, wholesalers, or destination management companies to solicit you with aggressive or deceptive tactics for congress registrations. 

They may also misrepresent themselves as the official congress registration and housing bureau and may illegally use the congress name or logo. Please be aware that such companies do not represent PRES or MCI and are not mandated to act on their behalf. 

If you are contacted by someone asking if you need to register for the PRES 2026 Congress or need a room, please do not complete your registration and/or room booking with such entities and do not process any of the payments they may request. 

Registrations purchased in this manner will not be given access to the PRES 2026 Congress.

If possible, please obtain as much information as you can, such as the name of the company, the person calling and their telephone number — then contact MCI Suisse SA at pres.reghot@mci-group.com. 

Should you require further information or want to confirm the legitimacy of any deals or services related to the congress, please feel free to get in touch with us.
