Sounds like a plan!
I could suggest one leg... a McCrae/Rosebud weekend.
If you picked an aggregate weekend at McCrae you'd get 2 short courses on the Sat. afternoon (2.30) and could sail around the pier for 2 races at Rosebud on the Sun. I think they have 11.30 and 1.30 or there abouts.
The travellers would have time to travel on Sat morning and would only have to get the mast up once etc... and could stay in one spot and get 2 clubs.
There's an opinion and a thought for you.
