We were on the Golden Princess, Pacific Circle for 76 days in 2017 and bought wine aboard in different ports, they didn't seem to worry about it. We drank it in our cabin or took a glass to dinner with us.
Great to hear about your excursions. We are on WC next year and haven't been to Europe before so we are grateful for tips and places to go and things to see. Sounds like the trip is going well, even though you missed a couple of places. Was there time to go to Petra on your cruise?
