Only drawback is size but this room ranks in the top tier with only Bellagio and Venetian their competition (Wynn I hear also compares but never played there).
Depends on table. Some were tough, others average, and some ATMs. Good mix.
No issues or problems.
Never saw them needed...speaks for the professionalism and ability of their dealers. Always friendly when signing up for a game.
Not sure, never used/asked.
