I have a 12 hour layover in Doha. Besides the obvious security question for a Jew in Qatar (which has a clearly Jewish name in my Canadian passport), I'm wondering if there are any other worthwhile attractions to check out on a tight budget while there. Particularly, any decent locations to rent snorkeling equipment? The water in those parts seems like it would be clear and full of beautiful fish.
Any advice on security and attractions to check out are welcome!
