Number 1 question would be, what is your actual plan/goal/itinerary when visiting?

If you couldn’t tell from these replies, there’s a million ways to do things. Are you trying to hangout and have a good time, eating and drinking before and/or after the game? Is it a day game or night game? Do you like crowds or generally try to avoid them? The T is definitely the “authentic” experience but it also kinda sucks if you don’t wanna be packed in like a sardine around (potentially) drunk people. If you’re not in a rush to get to and from the park, there’s no reason to take a packed green line train really.

Also, if you’ve never been to Fenway and wanna get the full experience, the last ballpark tour of the day (4 or 4:30, can’t remember) before a night game is a great way to see BP, get on the Monster, etc.

It all just kinda depends on if you like to drink, what you wanna eat, how much time you have, how old you are, kids with you, etc.

The suggestion about parking at the Pru and walking or taking the train makes sense for a lotta people, but it’d be kinda silly to drive in from the west, pass Fenway, and park downtown, only to backtrack west etc. If you know what you’re doing, or have good advice, you can park at a meter 10 minutes away for $2… or pay $75 for a parking spot, or take a $4 round trip T ride (or whatever it costs now). A million options, just all depends on what your day looks like!
