My vacations start in middle of November. I have 17 days there at my
disposal. I am thinking of spending initially some 3 days in HK + 1 day
in Macao, then rest of the time in Thailand, - maybe 2-3 days in
Bangkok, a few days on the beach (where?? not necessarily in Phuket),

Plenty of beaches in the south of Thailand:

With various price levels. Also the south of Cambodia has beaches,
perhaps cheaper than Thai ones (just guessing, have never been there).

and rest of the time for sightseeing (what and where?).

There are the Thai historical sites. Have you ever visited Angkor Wat?
