What do you think about the sudden switch in summer programming from Rock Your Summer to Disney's Frozen at DHS? http://thedisneyblog.com/2014/06/26/an-olaf-summer-planned-for-disneys-hollywood-studios/
They should have fun. Try and visit on an off day (not that there are many of those). Either with EMH if you're staying on property, or without, if you're staying off property.
Yup, what is an off day in August? LOL We are staying at Kidani Village for 9 nights so we will get plenty of chances to see this.
