Yes Tappy certainly does sound inviting, as does Carkeek, although Carkeek could feasibly be done on a mean weekend mission, particularly with daylight saving upon us. But a long weekend is certainly needed for a good attempt at Tappy. 

That said, I've just found out that a group of 18 from the Tararua Tramping Club are booked and confirmed for Tappy this same weekend. They are also equiped for camping, but I think that the huts sleep about 12 and there is minimal camping space. We may also be leaving the ferry bookings a little tight.   

For this reason Carkeek remains an option, as does Whanganui bay for those that are interested, but we may be a little short for Tappy or opt to go a few weeks later?
