This is what I learned from my very first Vegas trip.
Stay at a hotel north of the strip. A short walk or monorail ride can get you to the strip in minutes. We booked a room at the Westgate.
Avoid all the come-ons. The Westgate was going to give us a free meal and a show for sitting thru a 90 minute time sharing presentation. Several artists were giving away their music. In exchange for an autographed CD, they wanted a donation.
Bring a cooler filled with beverages and sandwiches. You get complimentary beverages while you gamble, but not while you are in your room. And don't expect a microwave oven in your room either.
Seek out smaller/local casinos like Ellis Island and Brewery. Beer was 2 pints for $4.50 and breakfast is $4.
Hit this liquor store across from Bally's on Flamingo Boulevard for cheap spirits!
Spirit airlines offer ultra low cost flights. We paid $123 for 2 round trip tickets to Denver! They also offer a $9 Fare Club for exclusive access to Spirit's lowest fares!
Check rest areas and travel plazas for coupon booklets. The deals in there are often better than the Internet!
We recently found coupons at a Chinese restaurant in York Nebraska. The OAK TREE INN in North Platte gave us a queen bed plus 2 free breakfasts at Penny's Diner for $62!
