We just got back from 8 days of Disney and I definitely agree about the sunglasses. We had to buy some at Walgreens! One big thing I couldn't have done without was my backpack. I packed snacks for standing in line, our gift cards for souveniers, autograph books and pens and hand wipe individually wrapped and antibacterial gel. I put these things in baggies so my bag was organized and I didn't have to dig through the bag everytime, I just had to get a baggie out! It was very helpful. I also brought frozen and thawed juice boxes and water bottles and put them in coolers in the stroller. We bought uncrustables and put them in the coolers as well. Then if the kids were hungry, we could do lunch in line. On thing I saw someone else have that was a good idea was little activities books. At the shows you wait a lot in line not moving like for rides then you get inside and wait some more and that would have been nice to have. The light up toys that spin I brought in my backpack and would pull them out if I knew the kids would be scared on a dark ride. It was also nice having my passporter so if someone suggested a ride I couldn't remember, I would just look it up. That I left in the stroller. Sorry to go on and on! Hope it helps!!!
