You'll need a hall or marquee with at least a couple of 13amp power sockets, and ideally some form of stage to allow the caller and band a clear view of the dancers.
( If you're using a marquee don't forget you will need lighting! )
The dancers will need a reasonably-sized clear floor space, preferably flat, non-slip and not carpeted.
We would normally run a dance for 4hours, taking a 20min break midway through to allow caller, band and dancers time for some refreshment and a breather.
When making your arrangements with the venue you will need to allow at least 45mins for us to set-up (longer if possible) and a good 30mins to clear away at the end.
You don't need any previous experience to join in. The caller talks you through all of the dances and will choose dances to suit all abilities.
It is an ideal social gathering that can involve every age group and doesn't require you to have a partner before you start.
