Shuttle service from Laglio to Cernobbio Italy

Hi there,
We are hosting a welcome dinner for our sons wedding next week at a restaurant in Cernobbio about 20 minutes from Laglio where most of our guests are staying. We are just now finding out from our wedding planner that taxis at night may be hard to get. The event is from 7-10pm. Does anyone know of a reputable shuttle service that we could pre negotiate with to shuttle approximately 35 guests to and from our event?
