For those travelling by car and looking for accommodation in France (usually cheaper than in Geneva), there are hotels along the Jura in Saint Genis Pouilly and Ferney Voltaire.
It is possible to travel from Geneva Station (Cornavin) to the Salle Polyvalente and back to Geneva via a combination of train (to La Plaine) and bus (La Plaine to Dardagny). It is also possible to walk (20 - 30 minutes) through the vineyards from La Plaine to Dardagny, but the route is steep and best avoided unless you are travelling light and the weather is good.
Trains depart from Geneva Station to La Plaine regularly. Check the CFF and TPG web sites for details.
You must buy your ticket, single or return, at the station prior to departure (not on board the train).
