Parents when do you feel is the best time to take a trip to disney world?

5 is the perfect age. I took my daughter when she was 5 and went with a couple other people and if there was any rides she did not want to ride, I just rode them with the others that were with me. Her eyes lit up when we walked into the magical kingdom and I had tears in my eyes because she was so excited. Disney world is about the kids and my daughter had a full appreciation for it and a love of the princesses at this age.
