Start off at the Bass Pro shop and Silverton Casino next door for the buffet. It is at the South end of the strip past the airport on Blue Diamond road.
Then just take the overhead train into downtown (depends on where you stay) and start walking! Venitian is a must as is the Encore just to walk through.
Dozens of shows and you can get last minute tickets at booths along the strip for a discount, just be ready to go to whatever they have a deal on!
We don't gamble so just seeing it all and the shows are worth it, and of course Bass Pro.
