California Grill has arguably the best view, while the view from Narcoosee's outside porch is fine as well. When you arrive at either restaurant you can request a "window" table, but no telling if you'll get one or not. Being on your honeymoon may certainly help!! In case you don't, it's terribly easy to go outside and see the show. In fact, at Narcoosee's you might have to do that anyway. THe outside porch is level with the table area, meaning that if there are a lot of folks out there watching, your "table view" wiil be blocked and you'll have to go outside anyway!!
Timing is always a difficult matter, as no telling how long YOUR meal will actually last--assuming you get seated exactly at your PS time, which dosen't always happen.
Very generally, we try to make dinner PS at a place like CG about an hour or so before fireworks. So if the fireworks are at 9, we make PS at 8. THis has always ensured we're still eating (at some point in the meal) when the fireworks begin. But again-it could be different. Once we had PS for 8 and didn't even get seated until after 9!!!
Hope all this helped??
