That would be a tough one,
But I guess what I'd do,
Buy two small 1 or 2 gallon tanks and take both betta's with me,
For one week they'd be better with me in the small tanks where I can care for them then left behind and worrying to death about them and afraid of what I might come back too.
I would not enjoy my time away otherwise.
They may very well survive the time away but it isn't doing the fishs health any good.
