I haven't used the comp nights reward before and I wanted to use it for the late June dates. I know I need to redeem my loyalty points, then check if the dates are available. However, I heard there is a call-in service fee, if you call the hotel. I heard you can also do it on mLife.com. How do you do that? Is there a myVegas code I need to input when I try to book online? Thanks for any advice. I've only used the myVegas rewards for Freeplay and food thus far.
