And the answer is zero because he can have elves come out to meet him, bringing food with them, rather than bring the elves along with him. :-p

Except for this (from the puzzle page):

Quote:Waldemar can only travel with other elves.

This seems to imply that he must have at least one elf along with at all times. Elves must travel in pairs at all times?

I agree, like most puzzles of this type, it is worded loosely enough to make it impossible to determine all of the parameters.
