Important Message Regarding Housing Scams!

Room reservations for this Congress are handled exclusively by the OSA contracted hotel listed above. Phone, fax or email communications from any other company or organization, offering cut-rate housing for the Congress or stating that they are a viable alternative to booking directly with the hotels, are not affiliated with the meeting in any manner. Those who opt for alternatives to the official negotiated rates may find themselves at risk. Other groups report that after paying these types of companies, no room was reserved and their credit card was fraudulently charged.

For these reasons, and to support our efforts to give you a quality event, we highly recommend that you do not make any reservations through any unknown housing or travel company. Again, OSA has no affiliation with any of these room brokers.

Please report any unauthorized housing solicitations to Customer Service at
