Had in incredible time at Mickey's Halloween Treat with DW and 4-year-old DS as SD* last night. After 8 hours at DL, we arrived at DCA just before 6:25 and front gates were already open. Started to head to towards Paradise Pier and made it to the rope right before they dropped it at 6:30. Made a beeline towards Paradise Pier (normal speed) and hit at least four treat stops on the way (no line at all). Our bags were probably half-full by 6:45. I couldn't find any reason to wait in a treat line - whenever I saw a long line later in the evening, I would walk another 20 yards and see another station with no line. Animation Building treat trail was especially fun (and not crowded) - did that around 9pm.
First to arrive at the Boardwalk games - played all three of them numerous times (they all gave out a sour fruit bar as prizes - we had so many we gave most of them to other kids). As far as I could tell, all rides except Maliboomer were open (all shows closed). Walked on to Screamin', Sun Wheel, Golden Zephyr, Jumpin' Jellyfish. The back of the park was beautiful and serene for the first hour or so, with no lines for photo ops (lines were much longer later). Headed to Pirate Wharf around 8 - all the crafts were gone by that point. Bug's Land was crowded at 8:30 and waited ~15 minutes each for Chew-Chew and Tuck & Roll (those rides seemed understaffed... or staffed by the wrong person).
The candy? I may be in the minority, but I didn't really care what they had. Not having great candy keeps me on my diet. DS likes the actual getting of the treats more than eating them. All stations have a "healthy alternative" available, and I was happy to get the apple slices, carrots, and flat fruit (all of which were pretty yummy). At one point DS asked me for a "chocolate item", and I said, "I guess that means that I can eat the apple slices..." As soon as I ate one, he said, "Hey! Those are MY apples!" and he proceeded to happily eat the whole bag (okay, he also had a bag of Kissables later in the evening).
Lots of characters, great entertainment (especially the music & dancing by Monsters, Inc), fantastic theming - a delightful evening. Don't forget to show your ticket at the Mickey & Friends lot for free parking, even if you come earlier that day!
