I went to Las Vegas last month.

I prepared with a lot of coupons.  I stayed on Fremont St. (downtown).  I used less than 10 of the 100's of Las Vegas strip coupons.  I mainly used the coupons I had for downtown Las Vegas.

1) Two, 2018 American Casino Guide books (coupon section only w/ cards).

2) Two, Four Queens/Binion's Funbooks.  One was about half used and the other only has one coupon used out of it.

3) Coupons I picked up when I was in Vegas

4) Other stuff like 3 casino win cards (you buy them in gift shops)

The coupons are good till the end of the year (December 2018).
