Here's a post with a list of porn stars I've hired and a bit about the experience: https://www.companyofmen.org/topic/158411-hiring-porn-stars/page/9/#comment-867766
As you can see, most were good experiences. The names most likely date me, alas.
My experience with porn stars has actually been pretty good. As examples, Josh Weston (RIP) and Rafael Alencar were both very nice guys and great experiences. Saw both more than once.
That's true. I hardly ever think of that train option since trips to JFK involve enough luggage that I'm always in an Uber. And the train will be a fraction of the cost of a cab.
Eight hours is long enough to get to Manhattan and back for an hour session with your choice of provider who offers incalls, but that will not be cheap. The yellow cab flat rate is $70 but with tax and tolls,and tip is usually $90-$100 (each way).
