The Massachusetts Convention Center Authority has purchased 5.6 acres near the Boston Convention & Exhibition Center for $33 million; the land is earmarked for two midpriced properties and parking. Construction on the 500- and 400-room hotels could start by the end of 2013, with opening dates in 2015. Parking for both hotels is in the plans, and garages would be built later as the proposed expansion of the BCEC goes forward. Currently, the facility has just 1,700 guest rooms within walking distance, so the addition of the hotels would boost the city's competitiveness. In August, the Massachusetts Legislature authorized the construction of up to seven hotels near the BCEC, the first phase of a $2 billion expansion plan proposed by the MCCA.
