“We just spent two weeks of living hell driving out here”

Actually you only spent 1 week:

Day 1 ended with them in Missouri after Clark fell asleep at the wheel

Day 2 ended with them at Cousin Eddies

Day 3 ended with them at Kamp Komfort

Day 4 ended with them losing Ellen’s credit cards

Day 5 ended with them at the Grand Canyon after Clark drove the Truckster off the road

Day 6 ended with them in Phoenix after Edna died

And they reached Walley World on Day 7
