wow! thanks for all your great responses and advice, one thing I am sure of, my daughter will only be going on rides that she wants to go on.
I would give gentle encouragement for the smaller rides (but doubt she'll need it for dumbo etc as she enjoys rides like that, but she definitely wont be going on any of the larger ones, myself and my boyfriend don't like rides that spin a lot so Crush's coaster is out, i wish in a way if was more of just a cute ride through the ocean seeing the characters etc, she would love that!
Parachute drop is another no-go, i think she is way too small and i don't think i would feel safe, but the Ratatouille ride looks good! as does the slinky ride and I think she will absolutely love the Buzz Lightyear one where you shoot stuff!
I think me and my boyfriend will use the parent swap quite a bit, although i have been on the rides when i went to Florida 5 years ago so not too bothered about them personally but my boyfriend has never been so would really love him to experience them all!
