Ingress might in fact be able to get away with her own hair color -- it'd attract attention, but this is a resort world that draws people of all types from all over the 'verse. If you're wearing... oh, I don't know, body armor, or a chiton, or something that looks like a Halloween costume? You might want to consider dressing down.

(No tutu for Ingress, sadly.)

But dressing "oddly" -- that will be fine. I'd use the Halloween costume guideline as a rule of thumb.

And money has always been able to be changed by Bar in the past -- I can't imagine it'd be any different this time. :)
