This is a good start to your character but I think there could be more of him to be developed. Such as, how did he gain his cutie-mark? Who were his parents and did they serve a huge part in his foalhood? Do they still keep in contact? Are there any future goals he wishes to meet? What are his hobbies? Does he miss his wife and child? Does he plan on getting back together with them someday? What happened to the previous hotel after he moved away? Has he tried to become a more social pony or plans to? Also you put people instead of ponies.
