Hi Dan! Both the Downtown Disney and the Magic Kingdom locations of the
Bibbidi Bobbidi Boutique are set up as large rooms with several styling stations. All guests at the Boutique -- boys and girls -- undergo their transformations in the same room, where they sit in chairs to receive hairstyling (and makeup for girls) and are then spun around to see their new reflections in big mirrors. Girls have a choice of princess packages, and if they choose the Castle package, which includes a princess gown, they do go to a separate room to change into their costume. The Bibbidi Bobbidi Boutique offers boys a
Knight package that includes a spiky hairstyle and a sword and shield. You can schedule appointments for both your twins at the same time by calling 407-WDW-STYLE.
You'll see a lot more girls than boys in the Bibbidi Bobbidi Boutique. Another fun option for boys that you might want to consider for your son is
The Pirates League, where boys and girls are transformed into scary pirates. It's a really fun experience!
Hope this helps! Come visit us again at the Moms Panel if you have more questions!
