The Conference Secretary has learned that companies called Expo Hotel Services, Exhibitor Housing Services, etc., are contacting speakers and attendees of JSPP2020/APCPST20202 and offering fraudulent travel/hotel reservation services, pretending that they are the official travel agent of the Conference. We do NOT arrange your travel/hotel reservation unless we are specifically asked to do so by you. So, please do NOT give your credit card information to unsolicited travel/hotel reservation service providers.
