Happy Feet may from time to time bring in external providers so that children can be involved in different activities (for example ballet or soccer). These activities may incur additional costs but parents will be advised well in advance and participation will be optional. Special excursions will also be undertaken from time to time, and may incur extra costs, such as transportation or entrance fees. Parents will always be advised of the costs prior and with as much notice as possible. Again attendance for these trips will be optional.
