Jodey, I'm sorry you couldn't enjoy the Death Valley National Park Audio Driving Tour due to the lack of service. It's crucial to download and preview the app and tour beforehand since cell signals are spotty in national parks. If there's anything we missed or if you'd like to try the tour again, remember it never expires, and you can use it on your next visit. Or, if you prefer, let me know via the app, and I'll happily exchange it for one of the other 100+ self-guided audio tours available. Your experience is essential, and I appreciate your feedback to help us improve.
