With a group that big it may be worth the time.
You'll be making your own fun.
Otherwise you're going to do a lot of traveling to go to a bar (a unique bar - but still just a bar) and Negril has a plethora of bars you don't have to burn a day to get to.
Still with a large group of Newbies, the memories of the Pelican will probably last a life time.
With a group that big I think you'll be rockin' the Pelican and glad you tried it.
