Just back from the Holland America Oosterdam holiday cruise. This is one of the few Holland America ships that has a 100% non-smoking casino floor and I have to tell you it was wonderful! We did witness some tampering with the progressive paybacks on several slots while the cruise was going on. They were reset without anyone actually winning the progressives. Cruise ship casinos can reset progressive between cruises but are not supposed to during the cruise and certainly not while the casino is open and players are playing those machines. Very odd... Still had a great time with great food.
