or using your players card at Caesars.com
Cheapest stays at Caesars properties will be
The Linq
Harrahs
Ballys
Flamingo
and it goes up from there.
If you go between Mar-Oct the pools are open. After Oct. 31 most pools close so check on that if your wife is a pool goer. If she is, I recommend you budget for Flamingo as it has a great series of pools, weekends has a party atmosphere with cover charges that are waived if you are a guest.
If you eat at Buffets then the Buffet of Buffets pass from Caesars will provide the food for two days. It is cheaper with your caesars card but it is now around $50 pp for a 24 hr pass. I wouldn't bother with any up charges to get you into the Bacchanalia buffet at Caesars (it's good but not worth the upcharge IMO) and if you time it with a late dinner the first day, you can get 2 dinners out of it by going to an early dinner the next day before your pass expires. Other than the Bacchanalia I would rank them Paris, PHo, Harrahs, Flamingo but really Harrahs and Flamingo have nothing special but would be ok for breakfast/lunch and the dinners I would either do Paris twice or PHo and Paris. The World Buffet at the Rio is good but it is off strip and there is another upcharge if you want to eat the seafood.
Ellis Island BBQ is another recommended meal. Only one block off strip behind Ballys. If you are into Cajun shrimp then Hot N Juicy is now on the strip in the Miracle shops in PHo.
Le Burger between Ballys and Paris is good. There is also a crepe place if you want that for breakfast right across from the Paris buffet.
Cheapest breakfast around would be the La Salsa Cantina in the miracle shops. I believe they serve until 11 am your basic 2 eggs any way with toast (you can get toast or tortilla) and choice of meat with homefries is $4.79. Anyways breakfast with coffee will run you less than $15 for the two of you.
As far as discounts, show your caesars card everywhere you make a purchase on any Caeasars property, it usually gets you discount/earns you comps. If staying at a Caesars property, I usually zero my comps by using them all on my hotel bill when I check out.
If MGM properties are your thing then also check out the MyVegas app and on facebook. It's free to play and you earn points that can be cashed in for free rooms, buffets, shows, spa etc at MGM properties. It's not hard to get a free 2 for 1 buffet but watch the requirements, some rewards require a night stay at a MGM property. Other than that, over the years I have cashed in tons of points for free stuff through MyVegas.
For me, I don't think KA is worth the price. It's a good concept with a bad show. Neat rotating vertical stage but otherwise...meh. O on the other hand is the best Cirque show in Vegas. If you can take swearing and some bald humor, Absinthe is the other show I would recommend - it is cirque like but isn't a family show like Cirque and the audience participation will leave you rolling in the aisles. You can try for discounts at tix for tonight (they also have a $5 coupon online that you should print before leaving) but if you want to make sure you can go on the night you want (especially if you are going during high season) get your tickets in advance of leaving for Vegas. Honestly the best shows are going to be full price anyways. Also check schedules before booking because the shows will be dark certain days and sometimes they shut down entirely for longer periods.
