Really? We haven't cruised as much lately, but we NEVER had to have an ID, other than a cruise card. Depending on where we were, sometimes we took our passports, but usually I never took any ID at ALL, in addition to my cruise card. Eric usually took his, but I almost never had a purse, and never took my ID. The last time we cruised was maybe 3 years ago, but I can't imagine it's that different now.
