Can we leave our car with you while we are gone for a week? Is your parking lot secure?

No

I dont think thats a good idea! Also, if ur not staying at the hotel then its not fair on them n dont need to be responsible for ur car

My car was stolen out of their parking lot and they did nothing to help. The cameras in the area don't work.

Their parking lot is not secure. I stayed their for 2 weeks and nothing happened to our vehicles. Follow the usual rules of not leaving things in plain sight and I think you will be fine.
