Limit warning

Can anyone tell me if the warning that you are exceeding your allowed MyVegas purchases still shows up? I know in the past a box would pop up to tell me when I'd reached my limit and was wondering if this still happens.
No, I'm planning a trip out to Vegas in 6 weeks and I purchased 10 rewards and no warning showed up.
I can't use all ten, but I wanted to have a variety to choose from once I'm out there.
Thanks! I had done the same thing and wasn't getting a warning.
