Feeding frequency of Darts

[Ptindy]

Hey all, I have been thinking of getting a pair or trio of darts and read that they are fed everyday. Now, I'm 20, I odn't want to be home everyday haha, I would still like 2 or 3 nights to go somewhere so I was wondering if I get frogs, how long will I be able to go away for without them getting too hungry. I have a mister for my uroplatus who like high humidity so I will now have to worry about misting, and my cresteds get misted by my sister when I am away each night. I don't want to limit myself to a home body so how many days will they be able to go without food? Or can I leave food in the tank with them? I have read that they can over eat which is why you shouldn't feed more then they will take at a feeding, so any ideas? Thanks. I have left my geckos for 2 or 3 nights with no problems.
