Your friend must have experienced
Characters in Flight, the new hot air balloon experience located at Downtown Disney. This is great way to get a view of the entire Disney area. I went on the balloon last month and was able to see parts of all four of the theme parks.
The operation of the Characters in Flight hot air balloon attraction at Downtown Disney are:
10:30 a.m. to 11:00 p.m. Sunday - Thursday
10:30 a.m. to midnight Friday - Saturday
Characters in Flight is very dependent on appropriate weather
conditions, so at times of moderate to high winds, the hours may be
curtailed or suspended.
I hope you get a chance to try it!
