Re: Frozen Four - Where to Eat? Drink? Must See Stuff
According to the TD Garden website, for parking at the North Station garage, there’s a $42 flat rate if you arrive 2-1/2 hours before the event. There’s a phone number listed for additional information. I called.
Here’s the conversation (repeated essentially verbatim so you can make your own judgment as to how (mis)informed

the person who answered to phone was.
Me: When are you going to open for the Frozen Four tomorrow?
Her: 5:00
Me: But the game starts at 5:00
Her: OK, then we’ll open at 3:00
Me: So what happens if we get there before 3:00?
Her: We’ll charge you $62
Me: So if we get there before 3:00, you’ll charge us $62, but if we get there after, you’ll charge us $42?
Her: Right
Taking the website at its word, parking should be $42 if you arrive after 2:30. For those who aren’t familiar with the setup, the North Station garage is the most convenient, but there are others that are not far away (but they aren’t much cheaper). We may just take our chances at getting stiffed for parking because it’s really hard for my wife to get around and we can’t afford to do much walking to either get to the Garden or finding a place to eat.
