I'm looking at flight options for a trip I intend to take. The cheapest option involves changing planes in Doha, Qatar. The options are very similarly priced, one with a 3 hour layover and another with a 9 hour layover.
My nationality is such that I can get a Visa on Arrival (another question might be how much this costs?!). Am I permitted (as a male over the age of 18, not-resident in Qatar) to leave the airport when transferring from Qatar Airways to Qatar Airways flights? Given that I will arrive at 5AM and leave the city around 11AM, would there be much to see/do in Doha? Will heat be an issue in mid-May?
