First of all, sorry to hear about this. I hope you get your property back and certainly hope it's not an inside job...just nothing you can do about that and its bullshit the casino refuses to help. I'd go to the media, personally.....seems as if only bad press is the only way to get them to make shit right.

Many states have passed laws limiting the liability of hotels (thanks, asshole lobbyists!) in the event a guest’s belongings are stolen from within the hotel. If the hotel was negligent in its reasonable care to protect your property (i.e., failing to secure the building from intruders), the hotel may be responsible for stolen property.

For those going to Vegas this summer, here's some precaution I use (I have family in law enforcement, and grew up in a rough neighborhood, so plenty of tips I have gotten over the years) for your room:

- Make sure to try to fit as much shit in the safe as one can before leaving for extended periods. Make sure the pin isn't something easy, and when you lock that fucker, pull on it and make sure it's tight and locked. If you have electronics in there, make a spreadsheet of the make, model, and serial numbers for each. For cash, spread it out to show how much is placed in the safe. I'd also take a picture/video of the inventory in the safe, before you leave everyday (with timestamp), for reference. Although room safes aren’t impervious to theft, they can deter a thief. It can be difficult to assign responsibility when someone steals your belongings during a hotel stay, but a big part of that one can do on their own end, is to have evidence of the inventory lost as they often dispute that the most in these cases.

- For laptops/big cameras/anything valuable that can't fit in the safe...three things: backup any useful data (that way, if you get rolled you at least keep the data like pics, files, etc); for devices, I would recommend tracking software like Prey that way you can provide this data to law enforcement for them to track down your shit and/or the perp; and for extra precaution, before you leave the room for extended amounts, ask guest services if you can leave valuables at the front desk (but only if they have a policy that makes doing so safe).

- Hidden cameras are also an option, as TheXFactor mentions.

- Before leaving the room for extended periods, leave the TV on loud, the bathroom fan on, and the lights on.

- Before leaving the room for extended periods, leave "Do Not Disturb" signs outside on the door. Granted, for longer stays Vegas hotels has become more aggro in one not being able to do this for an extended amount of time for "welfare checkups" (thank the Vegas shooter), but again, you want the impression someone is in the room from the outside.

- Before leaving the room for extended periods, take a video leaving the room, locking the door, and literally tugging on the door to show its locked and closed.

I cannot believe I have to post this bullshit, and its so stupid consumers don't have more protections against this outside of insurance (which you really shouldn't have to pay for). Even with these tips, you still may not get reimbursed...but at least it gives a victim ammo in the media/court.
