If you don&;t; I don&;t want to go to a theme park. I want to know what type do you like? If you only have one day, you can go for a walk in Shenzhen Bay Park, blow the sea breeze, or rent a bike in the morning. Then walk (or take a taxi) from Shenzhen Bay Park to Happy Coast, a new business district with cinemas, restaurants, shopping malls and so on. It&;s big and beautiful. You can go for a stroll. Then go to Ocean World to see exotic customs. If your English is good, you can chat with foreigners in any bar there. Most of them are foreign restaurants, there are many foreigners, and there are water curtain performances at night. The environment is very good.
