Planning to book with miles Biz class arriving from US in DOH at 10:30 PM, onward short-haul Biz next night at about 8:00 PM. Other than slumming in AM Biz Lounge, what can one do? Is there way to sleep for few hours in this lounge? More importantly are the free city tours still operational? Will my checkin be booked through to destination or do I have to take it out and lug it around since it's overnight? Based on the response, I will either book this or book with less layover but will have to swap the short-haul biz to short-haul Y. Please suggest. Thanks.
