I will not even consider moving them to a 10 gallon....
Either do not feed the fish or get someone else to feed them.

What size are they?
I agree with what everyone is saying, leave them where they are. If they are baby's I would want to feed at least every other day. Pre measure the food in ziplock bags and place the bags on the corresponding tank. Should take all of 30 seconds, dump and go. I always do a large water change the day before I leave just I case they get the bright idea to a another bag.
Great at to read your decision. Have a good and safe vacation. Fish will be ok !!
