Regent announced a new Grand Voyage Sydney to Hong Kong that includes 15 day land trip to China. Unsurprisingly, this is the same 15 days that Regent is chartering the ship for Chinese. This looks like a good deal if you haven't spent much if any time in China.
I am really pleased that Regent has gone back to offering Grand Voyages. On our Rome to Beijing trip last year we had to arrange our own Indian and Chinese visas (and pay for Vietnamese and Burmese visas) wherein in the past that trip had been a Grand Voyage with visas included.
Here is link to itinerary (not many specifics on land package yet):
