The building

It stands at 55 Davis Square, 6.7 km (4.2 mi) from the centre of Boston.

A stated 516 makes this a breakout or workshop room rather than a plenary space.

Access and arrival

10 km (6.2 mi) separates Crystal Ballroom from Logan International Airport (BOS) — normal for a city venue, and worth a line in the joining instructions rather than a shuttle contract.

At 6.7 km (4.2 mi) from the centre of Boston, plan on transport between the hotels and the venue as a line in the budget rather than an afterthought.

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.

The kind of event it takes

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 30th 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 516 covers most community and member meetings.

The app bill, at this size
