Does it matter which Ceasars casino I sign up for Total Rewards. Will be staying at both the Paris and Rio. But I know sometimes there are offers like free play for joining comp systems. Also didn't know if I should sign up by way of apply for the credit card. What do you think is better. I'm about 1 month out from the trip so I'm not sure if the credit card account can be setup in time or not before my trip. Thanks.
