Thank you all for the wonderful suggestions, info, and pics! It's nice to have visuals so I have a rough idea of how large the pieces are.
My bf and I actually were planning on taking it home with us instead of eating it in the parks. That way, we can eat as many goodies as possible while at DL, then still have something to look forward to when we leave! We have a 6 hour drive as well, so we'll see if the fudge will even make it home.

We might buy the packaged fudge if it's available when we go, but I kind of wanted to try some of the fun flavors that DL has to offer, so we'll see. Thank you all again for the help!
