We did a fortnight aboard Aurora in June last year and are also taking a similar trip to yours on the same ship in September of this year.We have also done the same cruise as you aboard Oriana,Aurora's sister ship a few years back.
If I can answer any of your questions please ask or I can give you a couple of useful discussion clubs where the people are mainly P.O. cruisers and discuss matters about the P.O> ships.
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.
