Damn it, I wrote up a long reply but I was timed out. To sum up what I wrote before it got deleted:
I am going to Antarctica during Xmas of 2017. I got interested a few years ago, especially after reading Endurance, and had a hankering to book it. My research led me to Quark Expeditions and I waited for one of their 'sales.' I got $3,000 off and had to only pay a 5% deposit, but also opted for camping and kayaking, which added another $1K to the trip. The cruise will be 12 days and cost $7,500 but since I booked it in June or July, I have 15 months to save up (~$400/mo). Since I just finished grad school, and paid my way through it, I am used to having my paycheck disappear so I am excited to do it. All of the flights will be paid for with points and I will combine it with a trip to Iguazu Falls (SPG for Sheraton there) and somewhere else in South America. Hopefully i'll be able to post a trip report in 14 months or so!
