Reserve Your Hotel

Beware of external (pirate) hotel booking agencies!

The SSSA Annual Conference official hotel is the Sonesta Rittenhouse Square, and the official and only SSSA-endorsed means to book accommodations is through the link above.

SSSA does not outsource its hotel reservations. However, companies or individuals are sending phishing emails to some SSSA members and SSSA Annual Conference attendees claiming to be able to book their accommodations. This is a common—albeit unwanted—occurrence for conferences and trade shows. No third-party company is authorized to arrange hotel accommodations for our events, nor is SSSA in any way generating these messages.

If you receive an email offering to book your hotel accommodations for the SSSA Annual Conference, please do not respond to it. By responding–even with a request to unsubscribe–you confirm that your email address is valid, which may increase the likelihood that you’ll be contacted again.

If you have any questions, please contact us at info@sotossyndrome.org.
