After stuffing dozens of $20 in their $1 slots with the biggest payout at $40, there was one $20 bill that didn't register in the bill validator. A young attendant then fiddled with the validator, put in another $20 that did register, took the money out, and then told me that since his $20 worked, then mine would have also worked and he could do nothing for me. He insisted that he wasn't calling me a liar, and then refused to get a manager to help me. I had to announce this robbery to the nearby patrons to then get the manager to appear with a bunch of goons that looked ready to toss me overboard. The manager must have checked the cameras and saw that I was the highest roller they had, losing over $1000 in just about 3 hours. So, he came over with 20 coins and said the attendant was wrong. On the return trip, I met a very elderly couple that had the same problem, but was rudely dismissed and never got reimbursed. So, this place is not only ridiculously tight, but is also a place for high-seas piracy. Unregulated, no laws to protect you at sea, this place is a nightmare I'll never go back to.
