I was actually wondering the same thing (we're going in July). We will start with base tickets and add hoppers if necessary. I did learn last summer that if you add hoppers you get charged for your full length of ticket (even if it's the last day). So, if you do decide to add, I'd do it earlier in the trip to waste as little money as possible. I ended up getting some pixie dust because I didn't know that and really wanted to park hop on our last day just to go see a night show in another park. The CM at guest services at Epcot changed the computer to think I had been in HS all day so that I could go over there for Fantasmic. I had to fill out all sorts of paperwork saying I was acknowledging that Disney did me a favor and never would again, lol.
