Yeah more fuel! Your food must be freeze dried/dehydrated to be that light- so more cooking & therefore more fuel. I think I'd take a bit more food too

Did you have some sort of camp shoe- like crocs to wear at the end of the day around camp/the huts?
Some sort of packtowel/chux?
sunscreen, bug repellant ?
Alcohol hand gel?
Cards/book some sort of entertainment maybe?
Gaiters?
