Safari is ok in my opinion. Worth the money. But taking a taxi or grab from the center of Bangkok to safari is a minus point. Because the driver will ask if you have booked the ticket online or not? If you answer yes, they will cancel the trip and not take you. I tried to book 10 trips but they were all canceled, then a driver told me that I should say I had not booked the ticket online and buy the ticket when I got there so that the driver would accept the trip. I had to lie to the driver, and when I got there, I had to pay the driver double the fare so that they wouldn't be upset.
