You'll probably want to check out the WoC superthread by Hydroguy for tips but here are some of mine if you don't want to read through all of that thread:
~ The closest spots are not the best viewing spots. You need to stand a good distance away to see all three frames.
~ The best section is Blue, followed by Yellow and then Red.
~ Forgot about lining up way before DCA opens to get tickets. Guests who stay at the Disney resort properties get dibs on the tickets at opening plus the tickets for the Preferred Dining packages are mostly for the first show. Instead, try to get tickets in the Blue Section (best section) for the later shows.
~ If you have a fast pass in the Blue Section, stand on the handicap ramp next to the rail for the perfect viewing spot. Most people rush to the front not realizing that they will not be able to get a view of the full show as they will be too close. The handicap ramp is slightly elevated so that you can see above everyone's heads who are standing up front and it allows you to get a full picture.
~ If you get a fast pass for the other sections, you will want to line up at least 15 minutes before the actual return time stated on your ticket in order to get a good spot. Although Disney does not officially allow people to line up before the return time, a lot of people hang out in the area before the indicated time and they all rush for the line once it opens up.
~ In the event that you do not get a good viewing spot (i.e. stuck standing behind someone who is 7 feet tall especially if you are short like me), consider going in the Wet Zone for a better view. Keep in mind that you will get wet...really wet but it's better than looking at the back of people's heads (bring/buy a poncho if this is your plan).
~ Keep in mind that you cannot save spots for people so have your entire party with you when you line up.
Have fun!
