DH & I were surprised that fireworks and Fantasmic are not shown nightly. Check out your schedule and make sure you see them. With four days, you s/b safe. But currently fireworks/Fantasmic is only Friday & Saturday. I think Sunday too, but don't know for certain.
Use EE if possible. EE was not available at all for DCA. And while we were there, no EE on DL for Wednesday, Friday & Sunday.
EE is the way to go at DL!
We watched Fantasmic in the crowd, off to the side. You do miss some of it this way. We also watched the fireworks. (Better than WDW, IMHO)
And then we watched Fantasmic again from the balcony (desert buffet). I forget the cost -- $30 - $40 something. Worth it? The view is great. Just depends on how badly you want to see Fantasmic. I probably would not have, but am not sorry I did. DH LOVES Fantasmic and thought it was worth every penny.
I posted our trip first day on the DL reports board. You may want to read it.
And the Eureka parade in DCA is VERY nice! They did a greta job. I read there is a regular meal buffet for that. (Like the desert buffet) But that was not necessary when we were there. We sat on a bench right by the overlook at Grizzley Rapids and had great seats. We only camped out around 20 minutes before it started. I think most view this parade from Paradise Pier.
