Yes! Near the Starbucks Central Area beside the escalators

When I was there in Nov, I saw a notice at a customer service counter showing that they did not provide service of luggage storage, and I did not found lockers. Most probably, there should be no luggage storage at that mall, but you may directly check with them.

Hello. Just Ask the hotel to call a taxi which is easily going to be a Tuk Tuk, a red van with benches. They'll take you anywhere. Plus the receptionist could get a fair price with the driver for you. Hope it helps.

I truly hate correcting the previous responses but, the Central Airport Plaza as well as other malls in Chiang Mai open at 11:00 am and close at 10:00 pm. I have arrived to many times at 10 in the morning and had to wait. I double checked today on google.

the free shuttle bus to Central Airport Plaza picks up from the following hotels: Amora, Imperial Mae Ping, Suriwongse, Centara Duang Tawan, Le Meridien, Shangri La, The Empress, Holiday Inn and Rati Lanna Riverside Spar Resort ... I will post a copy of the timetable (current 20.03.16)
