Depending on how “into” the game we get, I’ve had teams go outside to smoke, or into other rooms just to discuss strategy. Sometimes, this is a good 10 minute discussion before they return to the board.
If this keeps happening after each country goes, I generally propose that you get 10 minutes between rounds to discuss with your allies strategy for the upcoming round - but that no table talk is allowed during the round between allies.
Ends up being a pretty fair rule to keep the game moving, as after a single round someone most definitely needs a drink, to use the bathroom or to grab a smoke - which allows the 10 minute window to become more feasible.
