Ive been to Vegas 3 times since New Years. Things are starting to open back up.
By May who knows what shows will be open ect. .
They are pesky about maskson the casino floor so be ready for that.
Go down to Freemont Street one night. Just check out all the casinos most have been redone and its pretty cool. Circa is really cool.
Ellis Island for cheap filling meals.
Walking between casinos on the strip is often 10 to 15 mins to the property next door. A good walk from Venetian to like Flaming could easily be a 4 to 8 hour adventure if you hit up all the casinos and grab a drink or play a game, whatever.
Pai gow poker is easy and a game you can sit at for hours and not win or lose much. Of course at the Venetian it will be 25 a hand or so that could add up quick.
Rent a car. Ubers and cabs everywhere. Figure 20 a ride you won't be far off.
Hope this helps
