A big mistake is not taking photos of the hazard that caused your injury. Don't expect the dangerous condition to be there in the future. The hotel may fix it. I've seen hotels fix hazards within days after someone trips and falls.The time to take the photo is now. Don't wait! This assumes that you are still a guest at the hotel (or allowed to be on the property). You should not trespass to get back on to the hotel property. If you tripped over a change of elevation (a raised surface), make sure that the photo shows the length of the change. You can use a ruler to do this. Further below, you can see a close-up photo of measuring tape that shows the exact height of the curb (change of elevation) on a property. This exact height is important because if the change in height is too small the curb may not be considered dangerous. If you don't have access to a ruler, you can use a stack of pennies, or a deck of cards. Make sure that the photo shows the ruler (measuring the change in height). You should also take several photos from further away, and from different angles. Having a good photo that shows the change in height increases the chance that the hotel pays you fair value without a lawsuit. It may even increase the chance that the hotel (or its insurance company) pays you fair value during a lawsuit.
