We understand that you have many choices when making your travel arrangements. Please understand that reserving your room in the CII room block at the conference hotel allows you to take full advantage of the conference sessions, events and networking opportunities, and ensures that our staff will be available to help should you have any issues with your accommodations.

It has come to our attention that some of our conference participants are being targeted in a hotel scam. We do not utilize any third party hotel booking services. If you are contacted by any company other than Cambridge Innovation Institute (CII) or any of CII’s divisions (including Cambridge Healthtech Institute and Cambridge EnerTech) please do not do business with them. These companies may ask for advance payment, and should you contract with them, you may be unable to confirm, make changes or receive a refund, and reservations are often canceled without advance notice.
