Some general thoughts:
...
3) It looks like the best adventures to run will be Traitors, Sleepy Reef, Outlaws, Sleeping Volcano, Black Knights, and Roaring Bull.
Surprisingly Sleepy Reef has a high output so stock up on those.(It is not as high as it was when I first sent this.) BK and RB will be the go to as those can be swapped. Ali Baba's from woodcutter through third thief look to possibly have good rates so far. See
http://settlersonlinewiki.eu/en/even...om-adventures/ for the full breakdown of what is known. They only drop refills for your cemeteries.

Cemetary calculations
All pumpkin cemeteries can run the full 28 days, but I have only calculated for 27 days. They will disappear exactly at 28 days so don't wait too long!
Small: 4.5 runs every 24 hours, 121.5 runs for 27 days
So that means 121 pumpkins unbuffed, 363 x3 buffed, and 484 x4 buffed for each pumpkin cemetery.
They start with 40 pumpkins, so you will need 81 refills for each cemetery.
Common: 9 runs every 24 hours, 243 runs for 27 days
So that means 243 pumpkins unbuffed, 729 x3 buffed, and 972 x4 buffed for each pumpkin cemetery.
They start with 80 pumpkins, so you will need 163 refills for each cemetery.
Noble: 36 runs every 24 hours, 972 runs for 27 days
So that means 972 pumpkins unbuffed, 2916 x3 buffed, and 3888 x4 buffed for each pumpkin cemetery.
They start with 100 pumpkins, so you will need 872 refills for each cemetery.
Total refills needed for all 9 cemeteries: 3348
Total rainbows needed to run all 9 x4 buffed for 27 days: 63
If all are run at x4 consistently for 27 days: 19,920 pumpkins
To get all buildings and the recipe in the shop: 16,995 pumpkins
What to take away from this: Save up your adventure cards, make map fragments to buy those cards, save your rainbow snows, and save your collectables for Werewolf howls to run x4 when you don't have rainbow snows.
