No queues, no ticket collection.
Its a mini parade which stops in the place des stars. The CM's get the children to sit down in a square around the area the HSM characters will be performing in, and adults and others stand behind the children sitting. Then the show begins, songs and dances from both shows, theres some interaction with children who want to participate during it, and thats it really. Its all over in about 15 minutes, but its very enjoyable (bet DH sings along, however much he professes not to want to see it

). HSM and HSM2 are alternated during the day, every day (they are scheduled to show 5ish times a day total), so you could see both more than once in one day if you're having a Studios day!
