Hi Trisha,
I find booking the Fantasmic! Dinner Package one less thing I have to stress out about since I know we'll have reserved seats for Fantasmics, but of course, then the decision about which restaurant is more stress! If you haven't looked over the menus, I'd start there. A description of what is offered at Hollywood & Vine's (H & V) dinner buffet can be found
here. Mama Melrose Ristorante's (MMR) dinner menu can be found
here; the kids' menu
here.
What I think really separates the two restaurants is that H &V is a buffet, so you can eat almost immediately once you are seated, you'll have lots of choices, and the kids can eat off the entire menu (not limited to a kids' menu), but you have to work more to eat. There are sometimes at WDW after extensive walking where I'll admit I just want to be waited on (kind of embarrassing to actually write that, ug), especially when my children were younger and I had to help them with their plates, too. At MMR you'll be waited on, but with that comes a longer wait for food as well as the limitations of the menu. With all that said, I recommend both restaurants and enjoy them both. If you'd like more feedback, a quick search of each restaurant at www.disneyfoodblog.com will give you some more insight.
