Fellow Kerbanauts, lend me your ears!

For those of you who have made it to Duna… Would you recommend the placement of a refueling platform in the region of space between Minmus and Duna to ensure I have fuel enough for my 5-man crew to get home, or carry extra fuel with me on the cruise stage?

Carry more fuel. Realistically, you can only refuel around either Kerbin or Duna themselves. And coming back to Kerbin you can just point at the ground.
