¿Esto suena natural? Hoshino Resort has focussed on high class resort areas like Karuizawa, Okinawa and Kyoto. Recently they surprised economists by buying a major city hotel chain, ANA Crown Plaza, for 40 billion yen. The chairman Hoshino believes that people's preference is clearly changing; they want to stay in the busiest parts of big cities, enjoying concerts, stages and shopping. They also prefer eating out at fancy restaurants, choosing their own food, rather than eating the set course served at where they stay.

今回のは少し難しいですね。

「The Hoshino Resort focused on high class resort areas like Karuizawa, Okinawa and Kyoto. Recently they surprised economists by buying a major city hotel chain, ANA Crown Plaza, for 40 billion yen. Chairman Hoshino believes that people's preferences are clearly changing; they want to stay in the busiest parts of big cities, enjoying concerts, shows and shopping. They also prefer eating out at fancy restaurants, choosing their own food, rather than eating the set courses served where they are staying.」

There are a couple of choices for this phrase:
they want to stay in the busiest parts of big cities, enjoying concerts, shows and shopping. (そして＿＿＿）
Another is:
they want to stay in the busiest parts of big cities and enjoy concerts, shows and shopping. (parallel)

"has focused" だったら、"for many years"とか "recently"とかが必要。じゃないと普通の過去形でいい。

"The chairman Hoshino" → "The chairman", "Chairman Hoshino", "The chairman, Hoshino, "

"people's preference is" people's = peopleの (複数の人) なので "are"

"stages" = "shows"? "stage shows"?

"served at where they stay" - 不自然ですね。 "Served (at the hotel) where they are staying" など。
