Hi! Just wanted to say, I've been taking my kids to some of our trips to Disneyworld without DH since they were 4 and 6. He works a lot, and I am a SAHM (and love Disney), and I have had so much fun there even without him! There are always cast members and other adults around to talk to, and I also enjoy just hanging out with my kids.
I also like how easy Disney makes it, with transportation and so much to see and do. I definitely would recommend any single parent considering a Disney trip to look into it - sometimes I like it more when we don't have to worry about what DH wants to do!
