2361 Excel Files - Combine to 1

Need to combine 3 files from [login to view URL] which are hotel files. Need to make sure all match eachother. These files are from the [login to view URL] affiliate program. Main file has all hotel information second files has all the images, and 3rd has the descriptions. We need to make all of these into one and make sure they all match the hotel correctly to make one file. Not a hard job at all if you know excel. File will be verified before rating is submitted. Thanks
