This hotel understands group travel
Recently stayed at the property with a 50 person group. The staff and group director were all very attentive to the needs of the group and were willing to change arrangements on short notice. 
There are a number of good dining options in the arboretum area. This hotel is situated close to the arboretum but far enough to avoid the traffic issues. 
The buildings are in need of a renovation soon, but commendations to the staff and management on making the best of what they have. The rooms were clean and the bedding was updated. Some of the common areas just have a older look about them, but it's no reason to avoid the hotel. 
I would give this hotel a 3.5 if that was an option.
