See my last point, they're too busy/tired. 1/2 the people bring chips and salsa they picked up last minute on the way there.

People already maxxed want rest, isolation, catchup a breath on the very few long weekends. Those who do happen to have capacity want social media viable things to show off their status to their friends.
