My DD who is 4 did it in November and loved it! It was a great experience!!!
We did the biggest package (mostly because it was half-price at the time). It included- make-up, nails painted, face jewels (for boys they had all sorts of pirate face make-up including an all white skeleton face the boy next to us was getting), tatoo, a dress, sword, sash for the sword, hat, jewels in a bag, 3 pictures, and an official certificate.
They give each child a pirate name in the beginning and the CMs are REALLY into their roles and play up their pirate-ness. It was well themed inside and IMO much better than the experience we had the year before at the Bibbiddi Boppidi Boutique. It also was almost empty when we did it and reservations were easily made that day...I'm not sure if that has changed.
Let me know if you have more questions!
