The importance of booking your room in ACT's block
To ensure ACT meets its contracted agreement with the hotel, we request all attendees utilize the discounted room block we have negotiated as part of hosting the event in Philadelphia. ACT takes a financial risk when securing rooms for our attendees. Registrants reserving rooms at other hotels increase this risk, which could result in penalties for ACT along with fewer available rooms and higher room and registration rates in the future. In addition, holding rooms and canceling just prior to the start date impacts our contractual obligations as well. Make it easy on yourself and stay right where the event is taking place!
ACT will never call you about booking a hotel reservation. If you receive a call, even if it appears to be from someone on our Board of Directors, please disregard it and inform staff immediately.

Justification Toolkit
Attending ACT's International Conference is the perfect way to gain new knowledge, meet like-minded professionals, expand your skillset, and expose yourself to new perspectives and best practices in TDM. However, while you may see the benefits of attending an event, getting approval from management may take a bit of convincing.

Your manager needs to know your justifications for attending, plus the costs of travel, lodging, time away from work, and other expenses associated with the event. So, here are some tools to help make your case.

ACT will never call you to book a hotel reservation. If you receive a call claiming to be from ACT, even if it appears to come from a Board member or staff, do not engage. This is a scam. Hang up immediately and report the incident to ACT staff right away. Emails that do not come from the ACT staff should be discarded as well. Your security is our priority — stay vigilant.
