We were on the dining plan and couldn't get Mama Melrose for the pkg, so we chose H&V. Like you, I think it's fine but nothing special. Since we couldn't get Mama anyway and I wanted to sit down somewhere for dinner and I also wasn't interested in Sci Fi or Brown Derby (would have considered 50's but the F! pkg swayed me to H&V) I went ahead and did the H&V pkg. it was "fine" as usual for food.
I had never been to F! before and was very surprised at the giant mass of humanity at the entrance to fantasmic about 30 min prior to the show. It was very hard to tell whether there was any special line for FP or dining pkg people, until you get all the way up the incline to the actual theater and CMs there did a good job of steering standby, FP and dining pkg each to the right sections. Dining pkg seats are right in the center and very good location - I don't know, but I think all seats would be "fine", but pkg seats are definitely the best. It also seemed like there ended up being plenty more seats in the far right and left wings, but anything central was totally full.
All of this is a LONG way of saying we MIGHT have been just fine without the pkg, BUT I wanted my FPs for other stuff, I didn't have much else to choose from for that dining credit, and the theater seemed chaotic and full enough to make my reserved center section seem pretty great.
