Have you talked to the hotel manager? The parking lot is probably their property and they are responsible for what happens in it.

Alternatively, do you have full coverage on your car? If so, just call your insurance company and tell them what happened; they'll probably work something out with the hotel.

Other ideas: (I think) some credit cards cover theft if you use them for travel expenses and stuff is stolen while travelling.

The last thing you should be doing is tracking the down the items and trying to recover them yourself by force.
