We do both

I reckon Sofie won't be staying very long because she has a lot of skating to do

But we haven't decided yet what we're going to do to actually raise money, have we?
I thought we could do demonstrations throughout the entire day.
If we're with a lot of freestylers, we could split up in groups and demonstrate on different locations to cover a larger crowd in total.
If we decide to do this splitting up, I suggest we all come back together when Sofie arrives. For both entertaining and promotional purposes.
I suggest we definitely go with this plan as the "main plan" and have something extra:
* We could also give freestyle slalom initiations to interested skaters, and ask a small fee for it.
* We could cooperate with near café's to have roller-waiters and make some sort of deal with them that we get to keep the tips to donate to charity.
Any other suggestions?
