I got basically the same benefits buying my 2024 pass from Valleyfair, except for the slightly lower price due to exchange rate. It also worked out well because I was planning to be there on Sunday anyways, so I was able to get the physical pass at VF after buying it Saturday.
I also got the all park passport, all park dining, all park fast lane, and all season drink plan. I plan to visit Carowinds for the first time over Labor Day weekend, so hopefully all those benefits should work. The only thing that wasn’t clear on the website is if the all season drink plan that I spent $34.99 on is for all parks or just Valleyfair. I assume this is also what you bought and it does work at all parks?
Also, when I go to parks other than Valleyfair, do I just use my VF season pass everywhere to get in and use my add-ons?
