That's it? You just have to sneak past Elijah as he walks in and down the stairs? I thought it wasn't possible to pass through the force field.

I didn't have a stealth boy and don't recall seeing any (from the Wiki they are sometimes found in Dean's Stashes, maybe I missed one) so I'll just to console it in.

Didn't say what my P&Cs were:

Pros:

• Atmospheric
  
• Good characters
  
• Challenging for even a high level character.
  
• Well made, didn't notice any glitches
  
• Ghost people - weird and nasty
  
• Good back story revealed by the plot and terminals

Cons:

• Not keen on mazy locations where everything looks the same.
  
• Getting into the casino seemed to take too long and was repetitive
  
• Grand opening wasn't so grand.
  
• Too many find-key-unlock-door type searches.
  
• It's a pity that it's impossible to go back after returning to the Mojave.

A lot of it felt like a grind and personally I don't like the quest style but having got through it (I've yet to get the gold out) I find myself looking back on it with some affection. It's a well made and challenging DLC.
