5. When to go: Like WDW attendance at DLR goes up during school breaks and holidays. Weather-wise, summers are a lot easier to handle in So.Cal than Florida. While there are higher crowds at these times there is also a full entertainment schedule and few attractions will be down for refurbishment. If you are going in off peak times you may (likely) will not have fireworks scheduled every night and attractions may be down. One thing that is very different in DLR than WDW is the impact of annual passholder blackout dates. There are a HUGE number of annual passholders at DLR- I think the last number I heard was around 900,000. There are several types of annual passes and all but the Premium pass have some blackout dates; the least expensive passes do not allow entry during the summer peak periods. If you schedule a trip right before the blackout period goes into effect or right after it ends you will likely face parks filled with passholders. Hydroguy- the Jedi Master of DLR touring- also has a great thread on this. The World of Color (WOC) show at DCA is expected to open the first part of May. Disney is trying to figure out a way to handle the hoards of annual passholders that will come to DCA to see this new and much anticipated event. So this year, contrary to what you might expect, you will probably face lower crowds waiting until school is out and the blackout dates are in effect than going in May, when lots of passholders are going to try to see the new WOC show.
