The 135-room hotel, which employs more than 100 people, includes meeting and conference facilities and a business center as well as a fitness center, a full-service restaurant, a pub and an indoor-outdoor swimming pool. The grand opening also served as a fundraiser for Eastern Maine Medical Center’s CancerCare of Maine, the Bangor Symphony Orchestra and the Penobscot Theatre Company.
