We'll arrive at T2 Pudong Airport around 12:05AM, is there an available airport shuttle bus to use?

Our hotel is near East Nanjing Road station (line 2). We would like to use the subway but the problem is, it's already close by the time we arrive. Are there any other cheaper way to commute if airport shuttle is no longer available as well? Since taxi fare is expensive especially at night and we're a group of 6. Thanks!
