Being in Saudi is a very good opportunity to learn Arabic which will make your life much easier dealing with locals and other Arab nationalities around.
I am a native Arabic speaker with more than 20 years experience in teaching, 10 of them in teaching Arabic Language to non-natives especially Americans, Europeans, and South Americans. I use very easy effective methods in teaching and the course can be tailored according to your own needs; i.e. speaking only, listening, reading or the whole package.
The price and timing are a very reasonable and special discount for couples. Have many success stories in my CV for people who mastered the language and could use it effectively.
