If you're looking for convenience then the Westgate. If you're looking for style then any of the MGM properties as there is a convenient monorail that commutes between all those properties and the convention center.
Westgate
Depends on your budget
MGM Old is gold
Go Aria or Vdara if they are available. Easy to Uber over to the LVCC
Westgate is walking distance but kind of crappy.
In my opinion...mgmt is the way to go!
Westgate, travel lodge. Circus circus.
