Costs for Onboard Activities?

We are embarking on our WB TA on 8/31. Does anyone know if there is a fee for:

Dancing lessons

Fencing lessons

Yoga/Pilates classes

Also, if a passenger is inclined to tip for exceptional service, is it considered appropriate to tip the instructors for any of the above classes?

Please, I am not trying to start another tipping thread...:eek:

Thanks

No to the first two, although I think private dance lessons can sometimes be arranged for a fee.

There are charges for some exercise classes.
