My S85 is due to arrive on or near September 12th, and I park at Alewife. When I get in around 6:15am all 6 spots are usually empty so once I start parking there with my Tesla they'll be filling up earlier. If you've been parking there in the past and get in at a time when there are just 1 or 2 of those spaces left, it may be tougher to get a charging spot as of mid September.
