Hong Kong has by far the nicest beaches in S China, some really spectacular. Weather can be iffy though, but could well be perfect in September.

...... a long list of questions, you need to get a good guide book first, nobody is going to write one for you here on the TT.

To answer some Q's...... the village most famous for Saffron is probably Talouine in the Sous Valley south of the High Atlas, with Agadir at the western-end, Ouarzazate at the eastern-end with the walled and gated town of Taroudannt the most interesting town in the region lying 80km. inland from Agadir a city on the Atlantic.
This area with the seaside villages on the Atlantic south of Agadir are for the budget traveller.

For the sake of the children, the Atlantic has the best and most moderate climate, refreshed by on-shore winds off the Ocean, do some research here using the research facility above for villages like Mirhleft (a good area for camping and low cost accommodation), Sidi Ifni with Legzira Beach near by.

Yes, the caribe coast of CA can have opposite weather as the Pacific side, as well higher elevations too...

...... yes, Agadir where tomorrow the weather will be sunny at 20c. with similar to follow for a week or more.

Just north of Aberystwyth as far as the Dovey the beaches are sandy, & there are lovely sand dunes in the nature reserve at Ynyslas. All the beaches between Aber & Cei Bach (just north of New Quay) are shingle & very dull. Cei Bach itself is a good long sand & shingle beach with rock pools at one end but only when the tide is out. New Quay is a pretty village, especially out of season, the beach is not very big & doubles as the harbour. There are dolphin spotting trips from the harbour; these will probably only be running at the weekend in March.

Going south, Cwmtudu (pr. Coom-tidi) is next, a very small sand & shingle beach with a river flowing into it. Henry V11 is reputed to have landed here on his way to Leicestershire, (Tudu is Welsh for Tudor) also German u-boats during WW2 who thought they were landing on the west coast of Ireland because they thought that the Welsh they heard spoken was Irish. After that there is sand & shingle Llangrannog, picturesque with 2 good pubs, a cave & Carreg Bica, then Penbryn & Tresaith, both sandy & National Trust, Tresaith has a pub & shop and at the end of the beach is a very high waterfall. They are followed by sandy Aberporth, a very average village with lots of caravans, then Mwnt, also National Trust, very pretty with 100-odd steps down to the beach and a beautiful, tiny, historic church on the cliff above. Then there is Gwbert, where the Teifi meets the sea, and the other side of the river is Poppit, a long, sandy beach, great for kite-flying, cricket & football.

St Dogmaels, the village just before Poppit , has interesting monastic ruins, a working flour mill powered by water & a small farmers market on Fridays. Going further south, I don't know the North Pembs beaches so well, but they are mostly sandy & pretty. We like Solva, not a beach as such but a village on an estuary with galleries & antique shops, a good pub & an interesting line of lime kilns along the shore.

Keep in mind that July will be winter in Argentina. So not a great time to visit Patagonia, what with winter weather and so many tourist facilities being closed. Even Buenos Aires will be on the chilly side. Only in northern parts of the country like Salta, Jujuy and Iguassu can you expect warm weather in July.

Actually I am agree with alfredm about Casablanca. The only place I liked was just Sidi Abderrahman Marabout on one small island. Even if I admit that in Casablanca are more places worth to visit, but with your short time I would minimize the stay there.
To travel it is best with a rented car and you not need to have a driver, it is easy, roads are good, paved and signed also, so it is enjoyable driving. Follow the rules, don't drive in the dark and all will be fine. You can look at www.rentalcars.com, they have good cars, good prices and are trustworthy. I rent every time via this company and never had some problem anywhere.

P.S. You need 4 days fro the trip, not 3 days as I see now you plan to do.
Regarding the weather in the desert, late November is still fine, warm at day and not so very cold at night.

Sidi Ifni is nice place but a little far and you have not so many days anyway.

"You have heard of Accuweather, have you not? "

Of course I know them. They usually show the same weather for extremely dry and for extremely rainy areas of Switzerland and don't take into account that more than 3000 meter high mountian ridges can be weather barriers.
They manage to produce completely different forecasts for two neighbouring villages separated by a national border.

I can only offer two pieces of advice:

• if the weather is good, take the ferry from Bellagio or Menaggio back to Como
• the ferries we caught had both inside and outside areas

I can't offer any advice on castles or villas in these places.
