This is something interesting I found the other day, I almost forgot about it, but a recent post about Atlantic City on MW Loot Lady reminded me about it. I thought it might just be the solution for people who are stuck there. For anyone who is not stuck, you'll probably still find the bit about "Chapter 0" interesting :)
Go here to play Atlantic City unframed:

Now, use the following to travel to the different chapters (and leave a comment if this gets you unstuck):
Chapter 1: Uptown
javascript:(function(){loadPage('mobileweb?xw_controller=StoryMobile&xw_action=view&iframe=1&storyId=10')})()
Chapter 2: Broadwalk
javascript:(function(){loadPage('mobileweb?xw_controller=StoryMobile&xw_action=view&iframe=1&storyId=11')})()
Chapter 3: South Jersey
javascript:(function(){loadPage('mobileweb?xw_controller=StoryMobile&xw_action=view&iframe=1&storyId=12')})()
Chapter 4: Camden County
javascript:(function(){loadPage('mobileweb?xw_controller=StoryMobile&xw_action=view&iframe=1&storyId=13')})()
Chapter 0: ???
javascript:(function(){loadPage('mobileweb?xw_controller=StoryMobile&xw_action=view&iframe=1&storyId=9')})()
Notice that although the screen shot says "1: Uptown", the jobs are different, and quite possibly you will be able to master them for skill points. There's six jobs there, so you may be able to get 24 skill points. Please note, I take no responsibility for anyone getting stuck in Atlantic City (only for getting you unstuck) :)
