After doing it both ways. I would suggest doing the dinner package.

You can sit and relax and dine in the a/c while others will stand in line for probably an hour more than you. You still will want to get there little early so you can get a better seat, (so you can slide down, going towards the middle more). But if it's hot outside, most people have to stand and wait for a long time. When we did the dinner package at Hollywood & Vine(YUM! )

and we really enjoyed ourselves, then we had to walk over towards the beginning of the park (not where everyone is lining up at the front of the queue). You then show your tickets and you enter in the "back" . It is quite a walk, if you have some elderly in your party. But the walk was neat to see where most can't go and see. We got to sit down right away. Now I have heard others say they did wait in line, but not as long, like an hour as other have to without reserved seating. We didn't rush our dinner, so when we headed over to the show, they were already letting us in to sit. So we didn't have to wait in line at all. With reserved seating you are guaranteed a seat anyway. The only thing by waiting to enter, you are missing out more, on picking exactly where you want to sit.
Like Cinderella37 said, it's not a bad view, because it's shown in 3 major sections. So where you will be sitting in the RSVP area there is another water sprinkle there. And without giving away too much info away, there is a "parade" of items that come along the water, and they go through the whole water way in front of you. It's not like most shows where everything is centered. Although Mickey will stand at center stage a few times, he as well as everything else on stage in always moving throughout the stage, so all can see.
It's one of those things, if the park isn't overly crowded then, yeah wait in line, to have center stage, it's neater to be in the center, but honestly you aren't missing out by being on the sides. If anything you can get out of there faster being on the sides. LOL If you do decide to wait in the line, and not do the package, then go to the later of the 2 shows, tends to be less busy.
Love Fantasmic!
