I will be traveling to Vegas for work in September and wondering which is the better option for future comps: 1.) Book stay using MLife offers which at Aria or Bellagio would comp most of the stay or 2.) Book stay without any offers to boost the overall cost of the room giving more tier credits ... I assume #2 is ideal since I'm not the one footing the bill, just wondered if booking but not using offers somehow messes with the account. Thanks!
