It seems to me that Dan is looking for full pay games where $10 coin in earns one tier credit and one reward credit -- so he can maximize comps and tier score. In that case, the pay for a royal is secondary especially since a royal is a 1/42000 event for many games.

If you want to maximize your tier score and reward credits at $10 per point in Vegas then there is nothing wrong with going into the Palace Court slots area and playing one coin on a $25 8/5 Bonus or $25 9/6 Jacks machine. You'll get your 7 stars and your RCs.

To get the maximum of 5,000 earned tier points in a day, at a $25 game with one coin in, you would play 2,000 hands. That would also earn you 10,000 bonus tier points for a total of 15,000 tier points in a day.

Do that for 10 days and you score 7 Stars with 20,000 hands played. That's less than 1/2 of a "royal cycle" so why worry about what you would "lose" if you hit a royal? You're not likely to hit one -- so go ahead and stick to your plan to get your 7 Stars at the lowest possible cost.
