Looking for some ideas to celebrate my birthday this weekend.  Any favorite things to do or places to go?  Preferably a day trip, or a close overnight trip.

We don't have a car so need to be able to use the train, tram, bikes or our legs.

Current ideas on the table area as follows; if you have any experience/comments on them or better suggestions it would be appreciated!

1) relax by the lake + fondue dinner at Edelweiss (yes, its touristy!)

2) overnight at a spa hotel in Divonne Les Bains + spa treatment

3) boat ride to Yvoire + dinner in Nyon
