Sadly, yes. On 6/24/2014, after making the first part of my reservation at Mirage through Casino Marketing I just asked to be connected to Hotel Reservations. While waiting I remembered seeing something on LVA about a $10 phone reservation fee at Aria. I asked the Agent who answered. After a long pause she admitted there is a $10 fee for initially booking through her. She did mention some talk that the fee might be discontinued after summer. I thanked her and reserved on-line.
