Haven’t personally done it but I’ve seen other people on here and other sm sites saying that rope dropping her meet is the best option to meet her without a ridiculous wait time since she only meets until 3:00pm, I believe.
I think people have been heading over to where she meets near Dinoland at the tail end of the morning extra hours so that they’re amongst the first lot of people when she starts meeting at park open but I think even that has caught on now.
