Can anyone update me on The Resorts World.... Do you have to have a key card to get on the elevator...Which tower is best and is it worth it to try it out???

When I visited Hilton in resorts world I did not need a key for elevators.
The best one is Crockfords I cannot recall if key card was needed or not.
Yes definitely worth seeing but everyone has their own opinions.
Have fun
