Continuity mistake: When Cheryl emerges from the store and begins talking to the club representative distributing flyers, the lemonade she is holding has the cap off in one shot, then on in the next. It switches hands and then disappears entirely. The flyer she holds also switches hands.

Factual error: In the close-up shots as she reaches her destination at the end of the trek you can see streaked highlights in her hair right back to the roots. If she had been trekking for three months they would have grown out quite a long way, given the lack of regular salons in the wilderness.
Continuity mistake: In the first stage of her walk she can't heat water because she has a red gas canister, and the instructions she reads say she needs a white canister. She then buys a white canister at the next store, happy she can then heat her food. But then she is seen cooking with the red canister, which supposedly doesn't work.
