IF you believe (and more importantly, believe you can prove) that the hotel was at fault in causing the fire or allowing it to spread (maybe an employee carelessly tossed a cigarette; or maybe the hotel didn't have the sprinklers it should have had to contain a fire; etc.), you could sue the hotel for the value of your belongings. You have to prove fault to get compensation; a hotel is not required to pay for guests' damaged or destroyed goods unless  the hotel was at fautl in some way.However, the hotel is not at fault for lightning--they don't cause it or control it. So unless you can prove that the loss of your belongings was because the hotel was deficient in something to do with preventing, slowing, or minimizing fires--such as sprinklers or fire doors--they would not owe you any compensation.
