There are funny symbols on posts and signs on the treks in AK. I asked what they were for. The cast member said that they were for these new devices that they are planning to bring out in the parks "soon". You plug in the symbol and it tells you things like, where you are, where the closest washrooms are, what you can see around you, closest place to eat etc. as well as take digital pictures and keep your itinerary (priority seating etc.). She said that there were people using them to test them but couldn't go into more detail. Has anyone seen or used these? I asked the next time I went and nobody knew what I was talking about. I'm going at the end of the month and would like to know how to find out more.
