We will have what seems to be a fairly comment layover time in Doha, 5pm arrival and 3am departure. Traveling with our teenage son and very active mid 70s father-in-law. None of us have ever entered Qatar, only transited half a dozen times. We will have access the the Qatar business class lounge, but 10 hours seems like a lot there.

We love food and wouldn't mind seeing Doha, but most of the quick night tours I've seen are around $100-140pp. We've seen a number of souks in our life so the novelty of that won't be that great, unless there is something special I am missing. Are we better off just catching a cab and doing a DIY for a few hours then back to the lounge to get cleaned up for our flight? We'll leave our luggage at the lounge so will be traveling light.
