Hi Dillon,
It's difficult to say on this one. One vitally important question for you to discover, however, is "are there any attractions in Macau, other than Casino's?"... And by "attractions" I mean something like a theme park, or some great event, that could be thought of as an "attraction".
If there are, then contacting the promoters of these places or events would be your best bet for realizing the value that may, or may not, lurk inside of this domain.
If, for example, you contacted a theme park operator in Macau, who advertises internationally, and can see the value in a .com, then they could be willing to pay perhaps $1K-$5K for a name like this one.
Good luck,
