Thomas will always fly in a day early so you can rest easy the night before. Also, it is a point of pride for him to end his talks exactly on time.
If possible, Thomas likes to sit in on the talks of other speakers, allowing him to better connect the dots for the audience. He is also happy to connect with your other speakers ahead of your event.
Thomas also enjoys meeting participants after the session, and if the logistics allow, he is generally open to doing book signings, media interviews, or even short add-on sessions for VIP guests.
