perfect! thanks for your replies. i knew i wasn't the only single parent in the world to venture in to disneyland! 6yo was tall enough for most rides in florida last year so i'm presuming he'll be good to go in paris! he is a very anxious boy (poss aspergers/adhd) so i may give a uk theme park a go first to see how he'll cope riding by himself!
You will be fine, 6 year old may have to sit on own for some rides as some are for 2 persons per "carriage" for want of a better word. But there are the tamer sides anyway and some yet can squeeze 3 people in.
what it says on the tin really. done florida with family members who aren't willing to do paris. thinking of taking ds(6) & dd(4) with me as the only adult. will it be possible to do rides etc or do i need another adult?
