This worked very well in testing with a party of companions and associates. Note that I made the assumption that no-sleep triggers are tagged “RestTrigger”, warmth triggers are tagged “rest_warm”, and the food items have their localint “rest_food” set to 1.
// Place on the module's OnPlayerRest event.
/* 26/07/21 Kev. Deliverance modifications.
Desired results...
1. Player can rest freely, as long as they are not in a restricted zone (see d1_resting_restrict)
2. Any member of the party must possess a food item holding local var "rest_food"
3. Food item to be destroyed upon rest event
4. If resting creature is within a warmth trigger, apply well rested bonus: Full health/abilities restore, +1 fortitude until next rest.
5. If not resting in a warmth trigger, restore 75% health, restore all abilities.
*/
/* Travus 7/26/21 - Added code to check/remove one food item from the party when resting.
If resting in a warmth zone, the paty will heal fully and get a Fortitude bonus.
If resting outside a warmth zone, the party will heal only to 75% due the frigid weather.
Assumes all no-sleep triggers are tagged "RestTrigger".
Assumes all warmth triggers are tagged "rest_warm".
Assumes the food items have their localint "rest_food" set to 1.

Depending upon what you have done or allow to happen in your module will affect any edits a lot. E.g. I have a few puzzles that when I first did them, only the activator could access them. However, my players wanted me to make it so they could both see the puzzle. This added a few days work. 
And that was just one puzzle!
