Portland's convention business is doing very well and is far from being a "zero". Like Manchester, the city does not have a dedicated stand alone convention center yet. Meetings have been and continue to be held in privately owned spaces throughout the city and region. Greater Portland's draw will always be respectable due to lobster, L.L. Bean, lighthouses, museums, restaurants, OOB, transportation network and it's wonderful seaside location. I think the Holiday Inn by the Bay still has the the largest overall convention space in Maine at over 27,000 sf, for comparison purposes Bangor's Civic Center's meeting space totals around 22,000 sf. The Westin will have extensive space including a renovated State of Maine Ballroom when the hotel reopens early 2014.
