Kingston questions for my fellow Jamaica lovers

Hi All w'gwan
As all of you, I have been to Negril 30+ times...around there...lol
I am excited to be going to Kingston for a work trip! I am staying at the Courtleigh Hotel but after the conference I want to explore. I do'nt have enough time to go to Port Antonio so I was thinking about staying in Kingston or going to Green Mountains.
I was told to go to Hellshire Beach, and the Bob Marley Hotel and National Gallery..and New Kingston.
what say you Boardies? I really want to go to the Dub Club!! How do I get there?
Also other than Strawberry Hill, which is super pricey, is there any where else to stay inthe Blue Mountains?? Where should I go there? Is two days too much or enough??

Thanks so much Melissa
