I'm not going to be at Disneyland in June, but wanted to give a recommendation for something like my Peg Perego P3 stroller. It has a thingy on the back of it where a child can stand on it and ride while another child is in the stroller, so does double duty rather than purchasing a double stroller.
I got my stroller 5 years ago on clearance at a good price, but brand new full retail price ones can be kind of expensive. I'm sure there are other ones that might be more affordable.
