Is there commute available from New Chitose airport to Sapporo Odori park after 9.15 pm?

I am travelling to SAPPORO for the long weekend which is 21st to 24th. I have a flight that reaches new chitose airport at 9.15-9.30. I have a few questions

  1. What commute is best to reach Narita for a 7.30 pm flight?

  2. How much time before i need to reach the airport?

  3. Which line is better if I leave at 4pm from office to catch the flight from Narita? My office is in Mita, Minato-ku. I have seen there are multiple options like skyliner line, Narita express and asakusa line. Please tell me which one to take?

  4. Will there be any commute available from New Chitose airport to Sapporo Odori park after 9.30 pm? I saw a website which showed that the trains are only available till 4pm but google map shows last train till 11.20 pm. Which is the right one?

  5. Is it showing in Sapporo? Should I book my tickets to the snow resort?
