Travel to The Sinclair
9 km (5.6 mi) separates The Sinclair from Logan International Airport (BOS) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.
5.3 km (3.3 mi) out from the middle of Boston — close enough to book a downtown hotel block, far enough that people will expect transport laid on after dark.
Boston has 182 venues mapped in total and a population of 673,458. The Boston guide covers the airport, the local time zone and what else is bookable nearby.
What fits in this room
Think of it as one room in a bigger plan: a training day, a members' evening, a committee that needs to be in the same place. It is 29th of 182 venues mapped in Boston.
- networking mixers
An independent space with its own character, which a mixer benefits from more than a conference does.
- fundraisers and galas
A room with a personality is worth more at a gala than square footage is.
- community meetings
Room for 525 covers most community and member meetings.
A worked example for The Sinclair
Suppose 530 attendees claim their invite and open the app at a The Sinclair event sized to the stated capacity of The Sinclair. Here is exactly what event67 charges, with the free 50 taken off the top.

- billable, after the first 50 are free
- 480billable, after the first 50 are free
- for the whole event, at $5 each
- $2,400for the whole event, at $5 each
You are billed for people, not for the room, so this figure does not change if you move the event down the road. event67 has no floor-plan or booking product — the venue handles the space, the app handles the people in it.
