So believe it or not, I have never actually bought a SF season pass, as I usually went with the Platinum Pass for CF. However, as I plan out trips for the summer, I will definitely be going to GAdv and SFA, and I'm also lining up my Cali trip for SFMM and SFDK. That being said, it would obviously be advantageous to buy SF Passes. Now correct me if I'm wrong, but online you can buy season passes, and if you buy them through GAdv link (since that's closest to me), a pass in $79.99 or something. However if I go through SFA link, they are only $49.99. Both allow access to other SF parks, so my question is this:
Is there any hidden difference between the passes, or is it really THAT simple to save $30 just buy clicking a different park?
