GET THIS APP!!
Trust me, you need to get this App. It was the best tour guide for $10 bucks!! It works when you dont have service and somehow knows exactly when and where to inform you for whats coming up, where to pull over and what to look out for. We got the full version and used it all over the island. So interesting and wasnt an annoying voice like most! We seriously loved this app!!! We called him "dad". Best part is if you plug your phone into an aux cord when hes not talking you can still play your own music and he will just interrupt your music when he needs. Best thing ever!!!!
