Should I leave sooner than later for a birthday party in Westport tonight?

With it being Saturday as well as the No Kings rally (shout out to everyone who went!), I’m concerned about traffic and parking. I’m planning on taking an Uber or Lyft but wondering if the prices are expected to surge as the night goes on. I also haven’t requested a ride since before the pandemic so I’m not sure how much or little has changed. Thanks in advance!
