Finally someone who feels my pain lol. Last summer i went away and got my cousin to watch my 4 frogs and lizards. Obviously it wasn't an amazing job, but he kept them alive and well. You could pay someone you know like a friend or a relative (Most kids will do it because they love animals.) to take care of your Pac man, i mean if you teach them what to do it should go ok. Next thing you could do is buy a repti fogger and a light timer,the frog will be misted and the light will be good. You can feed him a ton before you leave and he will be fine. The water bowl is what it is though, just clean everything when you get home.
