But what if not possib

Your Umrah is valid regardless of the guide's creed, and the rites are short enough. Do them yourself from the booklets you already have, do not join in anything innovated, and you do not need to listen to anyone who suggests other than what Imam Ibn Baz taught in the book. You have internet as well and you can look something up if need be.
