I've done WDW alone for a few days by myself with children ages 4, 6, and 8. It was great! I was planning on doing it again this summer; but, babysitter really wants to come along. When I went alone, I explained to my older child that she would not be able to ride some rides since her brother was too young and she was okay with that. My husband flew down later in the trip for 2 days and took her on some big kid rides. WDW is so great for traveling alone with the kids. I feel so safe and taken care of. I hate driving alone with the kids (I always get lost) so I love the WDW transportation. Since my husband can never take a week off, I've decided that WDW will be our summer vacation every year. Right now, it's the only place I can imagine taking them by myself. Most people don't understand this and think I'm crazy for attempting it. But, these are people who stay offsite and try to cram everything into one or two days. We always stay on-site at Deluxe Resort on the concierge level. That makes everything so easy. And since I'm not paying for DH to be there the whole time, I can justify the expense.
