When we go on vacation, we have someone in the house anyway that has to take care of the cats, so I also have her take care of the fish.
I make sure everything is premeasured, ferts, food, and have the day of the week on each container that I use. Got some cheap small ones that work perfect from the dollar store.
Also have a line marked on my sump where to keep the water level at. First time I was very worried, 2nd time no worries, so I am hopeful when I go out of town a few times this summer, everything will go smooth.
The only thing I do worry about is that one of my fish like to eat from my hand, and did not have that fish the last time I went away. I hope it does OK for a week without me.
Good luck to you on whatever you decide, and enjoy your vacation.
