I've just returned home after doing a 100 day "half lap" of Australia in a camper trailer with my family. I made heavy use of gemini to plan much of it. Getting packed up with a general destination in mind and telling gemini "we're leaving X town at 10am and heading to Y, where should we stop for lunch. My wife has coeliac disease, find us somewhere that does good gluten free options" was one of the many things I regularly leant on it for.

Never had a bad suggestion.
