As I understand it, and someone will no doubt correct me if I'm wrong and I'll learn something new, you do not need to be online all the time when using the Adobe programs. The license checks are performed about once a month.
Mind you, I don't know if there's a way to "force" a license check before you travel to somewhere where you won't have Internet access for a while, nor am I aware of when during the month the checks are performed.
You could try contacting customer support to find out.
Edited to Add: See this link for more information. As I thought, you only have to connect once every 30 days.
to be sure, adobe cc requires, at least, intermittant internet connectivity. if you don't have that, you can't use adobe cc.
if you have intermittant connectivity, but not continuous connectivity, open the programs you want to use when you expect to lose connectivity and leave them open, at least, until connectivity is restored.
the typical situation is a laptop used for travel. eg, before leaving to travel with my laptop, i open the adobe programs i will (or might) want to use and minimize them.
that does mean, for users with more than one account, picking one account or the other. the only work-around would be using two laptops, each signed into a different account and each with that account's apps open during travel.
