Mmm.. ok.. even though the holidays are in this season... 
Are you going to the desert? You can access internet everywhere.... 
Maybe in your countries, you have access internet from anywhere, but some places may have problems in internet access which i faced this week. I'm a bit lucky that i did not lose any points in league. In one of the management games there is a holiday option(not in football but can be taken as a lead example).
You are selecting a user which is in friend list of yours, giving the time period and invite him for look after their account. If your friend accepts, there will be an option given to control which account. Your friend only will manage tactics. no financial operations allowed(sell-buy-upgrade). And all operations that your friends done will be logged.
I think developers can raise limit of absence with no penalty. Let's say half of the season.

Also if you are saying that, I can understand that you don't have any issue with inactive players.we are already blaming on inactivity. This type of holiday option increases the activity.
Also i'm against BOT-COMPUTER controlled assistants but this type of sitter option may be a good addition.
