We will go to Pentahotel Kowloon at 19 Luk Hop St from the airport. Is E22 bus better than A29 bus?

I know that E22 bus is cheaper but I am trying to find a bus that is more convenient for walking to the hotel after getting off the bus. Please forward a bus route map (for both buses) showing the stops if possible. Thank you.
Also, are seniors over 65 eligible for the discount fare if they take the E buses?
