Passage: I was planning a surprise Christmas trip to Disney World . First , I found the best inclusive deal with an on-site Disney Resort , and booked a 7 night stay which also included Park Hopper Passes . I called customer support several times to make dining reservations six months ahead of the date , as I knew they filled up quickly .

I planned early mornings because of my kids , with lots of downtime in the afternoons and a few activities in the evenings . I bought Mickey Mouse balloons , tied a letter explaining that we would be getting on a plane later that day , and wrapped it up in a large cardboard box with some Disney paraphernalia . I tucked it away in a corner for them to find after the initial rush of opening Christmas presents , knowing it would be the best present of all ! Question: Who did they devise a way to surprise? Option1: Their children Option2: Their animals

Their children
