We have done it before without the package and had no problem finding a seat. Although we did go a little early and the girls colored in little activity books and I graded term papers

while we waited. But this was the first week of December, slow season.
Last June we got the H&V package and thought it was ok. I was sweating though because I thought they might cancel fantasmic and I would have been upset to spend all that money on the dinner and no show!! Although I have heard that some people have been given tickets for later in the week. We never would have eaten at H&V for dinner if it wasn't for Fantasmic. Me, my mom and my girls just do not eat that much. We could probably have shared one adult meal and one kids meal elsewhere and been full!!!
I am undecided about this year, since we are going in August - the busy summer season. We've seen it before so I might just risk it without the package. I'm also interested in others opinions on this matter.
As far as eating at the boardwalk, I would either go for an early dinner or stay in the park. Last November we decided to go to Beaches and Cream for dinner on our last night since we had 2 Quick and Casual meal vouchers left to use. We left MGM early enough, or so we thought. We had to wait pretty long to get a table at B&C (45 minutes?). But we were already there so we decided to wait. After we ate, we were cutting it close to catch Fantasmic. As we left the Beach Club, a Friendship boat just docked. We ran to catch it but didn't make it. We figured by the time we walked to MGM, then walked all the way to Fantasmic theater, that we would be late. So we jsut skipped it. I was a little sad, but we had seen it before so I couldn't complain. We just headed over to Downtown Disney. So, the moral of the story is that you may want to stay in the park to eat.
