Pudong International Airport to Hangzhou City

2 adults + 2 kids (less 12 yo) + 3 luggage (L+M+S). Our major concern will be handling the three bulky luggage for the entire journey right from landing at Pudong Intl Airport to take Metro Line 2 from Pudong Intl Airport Metro Station to Hongqiao Railway Station Metro Station including changing at Guanglan Metro Station in between, then reach Hongqiao Railway Station Metro Station and transit to the Honqiao Railway Station to take the high-speed train to Hangzhou City. Please advise.
To do the above, we plan to land at Shanghai Pudong either around 0700 or 1500 on a Saturday, which is the better time?
Thanks.
