I've done a concert shop (for a favorite artist) during Christmas of 2016, an NBA game, and 2 MLB games for the MSC that does not have you leave a deposit. The best seats were for the NBA game (6 rows from courtside)....the first MLB game we were 3rd level left field and the other MLB game we were in the bleachers with the drunk fans (and it was an interleague game --- SF vs Oakland) so that was quite the experience). For the concert we sat in the 2nd level.
I won't complain about the report...yes its a bit long but if its for something you like to see then I'll spend that extra time doing it....and I did try and get to the venues at least 45 min to an hour before...which helps a lot.
Thanks for the heads up on the Boston games..my buddy and I are 5 MLB stadiums away from visiting all of them....and Boston is one of them,,...that's how I saw the SF/Oakland game last year @ AT&T Park through this MSC's shops.
