No,, sadly...
The Hobby pass lets you use GW's paints and bitz boxes for the weekend. The focused classes, like Basing or Blending are extra.
That's why I sprung for the Hobby masterclass, since it covers a range of specialist topics all at the same time.
Oh, and I was only able to get a King Sized room with a roll-away, so Hotel sign-ups must be popular.
