Not far from the Convention hotel is the Stratosphere where you will find probably the only full pay Double Bonus vp on the Strip. They are dollar machines, and pay 10/7. There are a number of places with 9/6 Jacks or Better on the strip, but usually at the $2 or $5 level. Watch for some places starting to short pay the Jacks machines with 9/5 pay tables (particularly Harrahs). Most 25c play on the Strip is a losing proposition, but if you're willing to go a few miles, you can find decent machines at some of the places like Arizona Charlies.
