Nearly 20 years ago I did this
http://www.surfaris.com/Was absolutely wonderful, back then we camped in the National parks surrounded by kangaroos and cooked over fires. There was no yoga, hairdresser and swimming pool* back then either. It was just starting up at the time so suspect it is the same operation.
I never progressed beyong standing up and going in a straight line. On the last day I was still faling off more regularly than standing up. I was probably just about the worst of the beginners, and a fair few were the opposite.
If you do start doing it by yourself, hire the big wide board. You aren't standing any time soon on a regular size board.
Might have to have another go if I ever go back.
