My husband and I are thinking of the Patagonia journey in Dec. 2026. We are seniors but relatively active. Why is the pace level a 4? Is it the long days? I’m a little concerned about the boat rides, I’m prone to motion sickness. I’m hoping since I don’t plan on ever doing Drakes passage to Antartica, Patagonia will be just as amazing. Any input on the journey would be greatly appreciated. Thanks
