Like you, I contacted T1J in regards to his proposed cruise that includes Antarctica and received no response. In addition to visiting Antarctica while traveling between Buenos Aires and Valparaiso, there will be another cruise early next year, round trip from Buenos Aires. I understand from my experience that it's difficult to find a cabin mate. If you are still looking for a cabin mate, we can share a cabin. About myself: 62 yo swm, from New Jersey, an avid cruiser, last week returned from a cruise around Galapagos islands. If you agree to share a cabin, please reply to me at your earliest convenience, as otherwise I'll use my vacation days on other options.
