Boardwalk Views and Standard Views almost all have some limited view of fireworks. Preferred views almost never do. So if you want a fireworks view, start by requesting BW or SV (which are guarenteed views - you book them when you book your room - they are also the most popular views - preferred being an oxymoron in this case - generally you need to book fairly early to get them). Then, the higher you go and the further away from the elevators you get, the better the view of the fireworks is. That's where the request comes in.
