We'll be there from March 28-April 3. Not only is it spring break for a lot of kids, but there are several large conventions in town as well. On the convention website it shows (39000/12000) natural trade expo from march 24-28, (30000) religious conference (3/30-4/2) and a few other little conventions here and there. I was also looking at park hours and they're open quite a bit longer than normal. Park hours mon-thur are DL 9-11 and DCA 10-8. Fri-Sun DL 8-12 and DCA 10-10. So it looks like it'll be one very busy week. On the plus side, we'll be having fireworks every night , weather permitting. Hope you have a great trip. We can't wait. Only 43 more days til leave.
