I like the Antarctica one - on the Explorer 14 Days, maybe with Easter Island,
I've actually lived in Antarctica on the peninsula for two winters and a total of 13 months. It's a pretty nice cruise they do to "the Ice" and you get to see a lot of the peninsula, and even the chance to stop by and visit my home away from home
Palmer Station.
I actually went to Easter Island, after my first winter on "the Ice" back in 2008, but not with Lindblad, but I heard great things about the optional side trip that they do there.
Machu Picchu and the Inca Land.... There are also a couple of land trips with Nat Geo I like the look of....
I actually did Machu Picchu and the Inca trail after my cruise last year, but not with Lindblad, but like the Easter Island trip, I heard that it's a pretty good trip. Too bad my friends and family deal, only gets me a discount on the cruises!
I like the cruise idea as it doesn't look at all like a 'suntan and screamers' cruise...
What was the average age of your cruise ??
I would say the average age was late 50's to early 60's, and this was a very "seasoned" Lindblad cruise bunch, meaning they have been on numerous Lindblad cruises, even the same cruise multiple times. I think we had 110 or so passengers (out of a 140 max), and they had a total of like 930 Lindblad cruises that they have been on. That's on average of over 8 cruises per passenger. Like I said that was my first, but many people had 4, 5, 10, 15, and then you have the outliers that have been on 40+ Lindblad cruises.
I'm in my early 30's and was the youngest of the passengers, but we had people in their 80's as well, that would get in and out of those Zodiacs for shore landings (I hope I'm able to that when I'm 80!). I never felt akward at all, even though I'm a lowly contract worker/unemployed vagabum, and people that I ate breakfast, lunch and dinner with, were not only millionaries, but multi-millionaries, that probably had my yearly salary, in their wallet in cash! There's also plently of people that weren't millionaires as well, but they weren't really poor either. They kept on thinking I was a part of the crew as a Naturalist, which was fine, since I knew a lot of the science/biology of where we were going even though I've never been there before.
While transiting the crew does a good job at having programs throughout the day to keep you busy and you'll able to learn the history and science of where you're going and what you'll be seeing. I even got a chance to meet Sven Lindblad the owner/president of the company, he was on the first leg of our three week cruise, and he's quite the character, to say the least.
