Registration for the TT2026 pre-meeting social event will open soon. We are currently finalizing an exciting program for Tuesday, 15 September, during which participants will explore Leiden and its rich scientific history through two distinct guided experiences.
Midway through the event, all participants will come together in a relaxed setting—an excellent opportunity to reconnect with colleagues and friends from the ISTT and previous TT meetings ahead of TT2026.
The event will take place from 10:00 to 13:00, leaving ample time before the official meeting begins to return to your hotel or further explore the city.
Stay tuned for more details regarding registration and event costs.
