I was in Aruba last month...
I went into the Crystal Casino (Part of the Renaissance Hotel) right on the main road in Oranjestad and I have to tell you that I was quite disappointed because in addition to the slot machines (Which I don't play) they only had one table game open (Blackjack) and that was filled with locals, You'd think with two cruise ships in port and tons of tourists walking around they'd have more gaming open, Needless to say I walked out empty handed which was something I wasn't planning on doing.
