I have done the buffet of buffets every time I have gone to Vegas. It really is a good deal. For those who are more on a tight schedule, I really wouldn't recommend doing this. You really have to devote one full day of doing this to get your money's worth.
The price with a totalrewards card puts your total to 49.99 without tax. Make sure you print your cards out before you get to the counter, or they will send you back to get it or charge you 54.99 and make you wear a tacky wristband.
START your buffet of buffets around 4-5. This gives you time to eat a late lunch, and maybe another dinner around 9. Most of the buffets close at 10. That's already two meals. Then tomorrow morning, eat breakfast, lunch, and you can also score another dinner. That's five meals for only $50! That's really a steal. With the high prices out here, you will definitely get your money's worth.
Recommendations: breakfast at Paris Hotel, dinner at spice market buffet in PH, lunch at harrahs.
The Banchanal buffet and rio charge an extra fee because their buffets are really well known.
