Tiaras N Tails doesn't just bring the party to celebrants' driveways, it brings a magical kingdom, too. The giant castle is painted on its air-conditioned trailer's exterior, along with a picturesque scene featuring rainbows and a lush landscape. Once the trailer pulls up, guests are invited inside, where the dressing room of every princess' dreams awaits. The interior includes vanity tables filled with hair accessories and jewelry and a closet packed with sparkly clothes, all fit for royalty. And once guests are ready for a dance party, they can make a royal entrance atop a real, live unicorn (or on sick days, a horse in a very convincing costume).
