My husband and I are now counting the days when we leave for our Mercury Valparaiso to Buenos Aires cruise on 1/20. Anyone else there who will be on this ship? I posted this once more than a month ago and got a couple of responses. Surely there are more of you. We would like to find someone possibly with whom we can share tour costs instead of using Celebrity's expensive ones. Also, can someone tell me which port is the best to see the penguins? Celebrity tour or otherwise? Thanks!
