Please be aware that there are several websites impersonating as the SIOP 2019 registration website. They can be very professional looking and may use online advertising to appear at the top of search results.
The only way to access the SIOP 2019 registration forms is via links on siop-congress.org or from the official SIOP Congress organiser.
Likewise hotels, we highly advise you to use trusted hotel service providers, such as the SIOP 2019 Group Booking service or the Official SIOP 2019 Hotel Deals website.
We look forward to seeing you in Lyon!

Please be aware that fraudulent sites are targeting SIOP delegates and we strongly advise you to use trusted sites.
