This might already be obvious to everyone, but I just recently noticed it. If you're wanting a park-hopper (on a regular ticket, without no-expiration), you can potentially save money by just getting a longer base ticket, and using multiple days in order to change parks. For example, it's cheaper to get a 10 day base pass than a 4 day park hopper pass! Assuming you are not trying to enter all 4 parks in the same day or something, and you're not going for too long, this will almost certainly come out better. In addition, if you are getting the "Plus" option, you'll get more pluses by making the base ticket longer.
Of course, going with the no-expiration option changes this around.
Hope this helps someone!
