DM Basics Friday Morning-Is it uncool to show up late?

[Cleric of Caffeine]

Hey all,

First time heading to PaizoCon & I'm crunching my schedule now.

Friday morning I'm interested in two seminars
-RPG Freelancers that runs from 8-9
-DM Basics that runs from 8-1pm.

Didn't know if it would be "uncool" to show up an hour late for the DM basics. Or if I could attempt a stealth check & get in without disturbing the host/proceedings.

DOH! Never mind just realized DM Basics runs 8-10 (still like to sneak in for the last hour)
