I never did end up using the BCCs - I just was never near them when I needed to pump. I had a nursing cover, I wore a pumping bra under a nursing tank every day - so it was easy to be discreet. My mom had made a soft quilted fabric case for the Ameda as well - both to help conceal it/discretion, and to help muffle the sound. Turns out the sound didn't really need to be muffled, ever. There was enough ambient noise everywhere that even I could barely hear the pump, and the person sitting next to me couldn't hear it at all.
I was able to find out of the way benches, for the most part, to sit down and pump at with little to no people around me. One time, though, I *thought* I had found an out of the way place to sit and pump, but it ended up being right in front of the exit for the Country Bears - so I was quite self conscious there. But I was using the cover, and no one could see anything, and I just tried to melt into the background as much as possible. I made sure to avoid ride exit points after that
Aside from that, I found a secluded sitting area up some stairs above the ice cream cart across from the rafts to TSI near Splash and Thunder Mtn, inside Innoventions (an out of the way bench), a bench near Restaurantosaurus at AK (near closing time, so park was dead), a quiet bench near Muppet Vision in DHS - and beyond that, I ended up pumping at our meals. Especially at CS meals, it was very easy to find a table in a back quiet corner. If I was allowed to sit down before getting food (sometimes yes, sometimes no - depending on crowds), I sat and set up while family ordered food for me. As I said earlier, even at the TS restaurants the noise was ambient enough to cover the noise of the pump so that I could barely hear it myself, much less anyone else.
