Rueda is NOT for salsa beginners. If you are thinking about doing La Rueda for the first time you should be competent with your basic salsa, i.e.
Doing Rueda is about applying and developing the salsa that you already know in a Cuban style and having a lot of fun in a group activity. Although it will undoubtedly improve your dancing and increase your repertoire of partner combinations it is NOT about learning basic salsa.
Absolutely. There are some differences between cross-body and Cuban salsa styles but as long as your basic salsa is ok then come along and have a great time.
Apart from having a lot of fun in the sessions and learning some group routines, rueda develops and improves your salsa generally and you will learn new couple combinations that can all be used in social free-dance.
Also bear on mind that Rueda pops up in social events, often quite spontaneously.
Absolutely. As with any salsa class lots of people come on their own. Although La Rueda is fundamentally a group dance for couples we can always manage when there are extras.
