I would be interested on knowing the sights to the discussion clubs you have mentioned. We have just booked to go on the Aurora in August. We were supposed to be cruising on the Millenium on the 22nd July but we found out last Thursday that it had been cancelled, so we are a little disappointed at the moment. We now have to start all over again looking at what to do at the different ports we will be visiting. If you have any advice I would be grateful of it.
