I would go ahead and purchase it to be sure. It is not much fun if some of your party have precheck and others do not. Also, some credit cards will cover the cost of pre-check. Worth a look at $85 each.
These are the ones I know about:
American Express platinum
Chase sapphire
Capitalone venture

You can also look into getting NEXUS though the interview locations are mostly located near near the Canadian boarder, though a few cities such as Seattle and NYC have places you can go. It's only $50 (compared to $75) and includes Pre-Check as well as Global Entry.
Note, Precheck and Global entry are perks of the Chase Sapphire Reserve, not the Preferred or Standard.
