Vacation feeding

My box turtles do fine when I’m gone for a few days but I have a vacation of 10 days coming up. Anyone have any experience on how to care for turtles while gone for an extended time? I have a water mist system on a timer that will keep them cool and most while also refilling water dishes, so I’m more concerned with food. I usually leave a lot of lettuce, pellets, and crickets but will this be enough for 10 days? I would love to find some way to feed them meal worms with an auto feeder but haven’t really found something that would work. Any and all suggestions are welcome! TIA
