Happy Thanksgiving, folks. If you're not into Thanksgiving, then Happy Holidays. If you're not into holidays, well, we can't really help you there. But here's what we can help you with this holiday season:

• Free registration + $10 off

• $25 off when you book in advance

• $135 for you and a friend

So really, even if the holidays aren't your thing, you still get to benefit from them. I know, I know. You're welcome.
