Thanks everyone of all the information. My head is spinning but I am going to keep it in mind for our next trip. In relation to the comment that you need wifi to use google maps for directions, I just wanted to say I use the MAPS.ME app, You can download anywhere you are going ahead of time or when you have wifi and then use the app for all info and directions you need with your phone in airplane mode. We used it on our last trip and it was fantastic.
