Getting there
11 km (6.8 mi) separates O'Brien's Pub from Logan International Airport (BOS) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.
6.2 km (3.9 mi) from the centre puts this outside comfortable walking range of any hotel district, so the shuttle is part of the event rather than an extra.
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.
Formats this suits
Smaller spaces are where most events actually happen, and O'Brien's Pub is one of them. A single-track day works; a programme with a trade floor attached does not.
- 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.
