I鈥檝e been doing occasional weekend day trip to Boston and have been parking at Alewife without any issues. From what I鈥檝e read on weekdays the parking garages fill up very early in the morning.
What time of day do the garages start to have free spaces again? If it matters I鈥檓 open to parking at any of the outer terminus stations: Oak Grove, Alewife, Riverside, Braintree, whatever. It doesn鈥檛 need to be Alewife.
There鈥檚 a weekday concert in mid September I want to see. If I knew I could reliably park sometime in the afternoon (or late morning), that鈥檇 give me the push to go ahead with getting a ticket.
When was your source for the garages filling up early? Sure, that used to be true, but you should make sure you have a recent source, post-COViD. It may also depend on day of week, since most of us who work part time from home seem to have core office days in the middle of the week.
I don鈥檛 commute downtown anymore, so can鈥檛 give actual relevant experience, except that things have changed, so more info will help
