They provide a great range of jumping castles for hire (including their new Disney's Frozen castle which is already been booked well in advance, so be quick!).
Marjo are a family owned business by the wonderful Marc and Josephine. As well as jumping castles, for your kid's party, you can hire out Pete the Pirate and Jo Jo the Clown -- two characters that are part of the Marjo family. They also have face painting and henna tattoo options.
