It depends on the beer you're making. If you allow the mash to continue dropping, the amount of fermentables will continue to increase because of the enzymes that will become active at the lower end of mash temps.

You also don't want to let it sit TOO long, or you start to extract tannins and off flavors from the grain. So if you're starting at 154 for a stout for instance, if you let it sit for two hours, you aren't going to get the body and mash profile for a stout if the temp drops down to 148 over the course of a couple of hours. Does that make sense?

That's not a problem at all. A lot of brewers (myself included) will set the mash and stabilize the temperature, then do whatever errands need to be done for a few hours (even do a full work day!) while the mash sits. If anything, it allows for more time for conversion to happen, which can only really be a positive thing. Happy brewing!

Some folks mash overnight. As long as the temp doesn't drop too much, I would not worry...

I heard Bud Light is mashed for more than three hours.
