Ah right, that's true, so my calculations are off.
140k/300 = 467 ornaments/candy canes (without bells)
467/4 = 117 maps/9 days = 13 maps per day, in other words, impossible without buying gift bags/resets.

Personally, if you're willing to spend, just grab Katy and PVT and call it a day. The event-only 5*s aren't worth the extra whaling and going for them will only impede you from advancing in the game (clearing the main map, especially unlocking oil/currency/metal tiles, and leveling)
