Alternative Prudential Parking
If you plan on spending a couple of hours of shopping at the Prudential. You should know that it will cost you $28. If you spend at least $10 at any store in the Mall you'll only have to pay $12 for 4 hours of parking.
This isn't much of a savings if you are planning on shopping outside of the Prudential, such as Boylston Street and Newbury Street.
An alternative to parking at the Prudential is to park at the Christian Science Center parking garage. There are two entrances one Huntington and another on Massachusetts ave. It's a short walk, 1/2 block, to the entrance to the Prudential Shopping center.
Current Parking rates for the Christian Science Center parking garage:
Up to 3 hours $15
Up to 12 hours $20
Up to 19 hours $30
Up to 24 hours $40
If your going to be spending a lot of time in the Back Bay for shopping or enjoying a nice day, you should consider the Christian Science garage. If your looking for a Taxi, take a walk down Belvidere Street towards the Sheraton Boston Hotel, you'll see a large taxi line up. This is a great place to grab a taxi since they can go in any direction from that location.
Garage Parking Tips: When you enter the garage, drive all the way in. The further you drive in, the less walking you have to do to get out of the garage. Take your ticket with you since your better off paying on the way out.
