It is very important to keep the Movie Theater because you can speed it up 10 times a day to get many coins. Also consider updating to a Water Park if you have the money.

The only sellable 3x3s you have otherwise are the multi-story buildings. 2x2 buildings require 4 squares and 1 road so a total of 5. With one road square 3x3s require 10 total squares. So 3x3 takes twice as much room. However, you will also notice that the 3x3 buildings produce much more in a shorter period of time. For example, Country Houses require 5 squares with 24 pax per 4 hrs while Multi-Story Buildings require 10 squares with 56 pax per 4 hrs. So the multi-story building takes up twice as much room but produces more than twice as much as the Country House. So I would definitely keep all of your multi-story buildings for the time being.
