Airdrops will change your journey entirely. Forget cold tents, slow and heavy travel, freezing rest days, no change of clothes, hairy preparations in terms of which backups to bring and which to leave behind, and the battle for supplies to last. The route will be easier because you'll be faster, and your schedule more forgiving. What you forgot you can order, broken skis are replaced with new ones and there will be a fried chicken thrown in for good measure too. If you had a good guide, you'll arrive at the pole rosy and fresh without even the smallest sign of frostnip. It is common even to gain weight!
While supported polar treks deserve respect in their own right – it is not a weekend trip in Colorado we are talking about here, they simply doesn't compare to unsupported travel in terms of challenge.
