I have been extremely fortunate when renting my cabin.  There has never been any major damage or breach of contract....until yesterday!  I rented my cabin to a couple for the weekend and the boyfriend signed the lease and made the payment.  My cleaning lady called and said that all the beds were slept in and it looked like there were a lot of people who stayed by judging the amount of alcohol that was consumed in the 2 days.  I e-mailed the boyfriend and asked how many people stayed at the cabin.  His exact response was:

"Well, I am not exactly sure.  I had orginally rented the cabin for my girlfriend and I.  However, we broke up earlier in the week so, I am not exactly sure who she brought".

I have no idea who was in my cabin...I don't even have the name of the girlfiend or how old these people were!  I kept the security deposit but my questions are:

What would happen if someone who was staying at my cabin was hurt on my property but was not on the lease?

What would happen if there was any major damage to my house while these people were there?

I am fully insured, have rental insurance and the contract is very detailed. 

Thanks for any input.
