Ocho Rios tour at the port-are there safe ones?

Can we hop on a tour at the port or are we best booking via the ship? Are there reasonably priced tours to go to Dunn's River , etc?:)

I don't think I'd hop on something there. Ocho Rios tends to be a little overwhelming. We've been super happy with Javia at know jamaica dot com ... no spaces. They have all sorts of different options and I have found the prices reasonable.
