NNS 2025

ACCOMMODATION

NNS 2025 Accommodation Now Open

A room block has been secured at the Philadelphia Marriott Downtown, the symposium venue, for NNS 2025 delegates. The deadline to book overnight accommodations is May 2, 2025 (subject to availability).

The Symposium Secretariat (International Conference Services) is the official housing bureau and will offer assistance with the coordination of housing requirements for NNS 2025. Special room rates have been negotiated and will be available to Symposium delegates only.

The success of the NNS 2025 depends on delegates, sponsors and exhibitors using the official Symposium hotel by booking through the official housing bureau. NNS 2025 cannot meet contracted room obligations if registrants reserve rooms outside the official hotels or book hotels through channels other than the official housing bureau. Rooms that are not filled through the official housing bureau create an expense for the Symposium in the form of financial penalties (attrition fees) and place the financial success of the Symposium at risk.

You must register for NNS 2025 before you can book your accommodation. Please do not contact the hotel or make a reservation directly with the hotel. For any inquiries regarding registration for Neurotrauma 2025, please contact the Registration Team at nns-registration@icsevents.com

Students Room Sharing Requests

Students will be able to apply for room sharing when registering for NNS 2025. Students will be paired with a roommate allocated by gender, and splitting the hotel bill will need to be arranged between the roommates. Unfortunately, we are unable to accommodate roommate requests for NNS participants.
