We stayed on the top floor of Sago Cay in a Standard/Garden View room. We could watch the monorail from the balcony and we liked this very much (My father is a retired train engineer- the monorail is his favorite ride.) Our room had 2 queen beds and a day bed. My sister, brother-in-law and nephew were down the hall in a room with the raised ceiling and no day bed. We liked our day bed room. They liked their higher ceiling room- it had a smaller, more enclosed balcony- my 1.5 year old nephew was able to go onto the balcony and play without all of us worrying and running after him!
One night there were extra fireworks for some event. I could see about half off them if I poked my head over the balcony. There are great fireworks views at the marina- I just watched these from the balcony as they were part of some extra event and later in the evening. We always stay in Standard/ Garden Views with Disney hotels and liked this view the best!
Have a great time!
