Thanks for all your replies guys. Looks like we've made a good decision to go to Reunion and my 3 year old is already asking to pack her case to go and see Mickey.........we don't go until March!

One thing to bear in mind for anyone using this thread for ref in the future is that the waterpark isn't available to guests who rent their accommodation direct through the owners as opposed to the resort. My owner assures me though that all other amenities are included gratis.
