Yes! We can’t stress this enough. Make sure you download the tour before you go (preferably at your hotel). You don’t want to get on the road only to have a poor data connection and no access to the tour or offline map. Remember, you'll be driving in some remote parts of Hawaii.
If you download the tour before you go everything will work offline. While you’re downloading the tour make sure you leave the app open. Closing the app or switching over to another app may stop the download or cause problems.
If you didn't download the tour at your hotel before you left, don't worry, there are still some options for you!
1) Find a spot with WiFi like Starbucks or a local coffee shop. Pro Tip - McDonalds WiFi is super slow so look elsewhere!
2) Can't find a spot with WiFi - go to a nearby city where data is likely to be stronger and download the tour over your data service. If you do this, we recommend you pull over and wait for the tour to finish downloading before you continue to drive.
