I recommend you to take a free day to visit the old Geneva (Vieille Ville). You can rent an audio guide that takes you to a walk visit through this amazing area. You can find more than 2 thousand years of history with buildings, museums and monuments. You can rent the audio guide at:
Geneve Tourism office
Rue du Mont-Blanc 18
