<prompt> Human: My family is doing a 60th wedding anniversary trip to Europe and related cruise. Ill probably give them a Citi Dividend card which gets me like 1 or 2 cash back I prefer cash to Miles, etc, I think....Is there anything in particular I could be doing to get better rewards for this big purchase? I cant choose the company or get it cheaper due to it being a family trip.  <response>: You have to make the purchase tonight, but youre looking now for credit cards to sign up for???
