Regarding your arrival concourse - it is correct that A380s do not exclusively park at the A concourse. It probably isn't worth scouring flight and gate histories as 1) A and B are connected airside by a shuttle train that leaves every two minutes and 2) as you have an airport hotel confirmed, if you tell them your incoming flight arrival details, they should have someone waiting to pick you up at the gate to skip you through the queue at transit security. If not, it is relatively trivial to get around DXB - just quite a lot of walking!
