Aloft Hotels, Arundel Mills (BWI), 7520 Teague Road, Hanover, 443-577-0077, starwoodhotels.com. Aloft, making its debut in May at Arundel Mills, strives for a cool vibe, demonstrated by phrases like "easy breezy" and "aloha!" But beneath this carefree facade is a seriously chic hotel. Vibrant colors cover the modern furniture in the lounge and exercise rooms. The hip atmosphere continues to the "re:fuel" cafe and "w xyz" bar, where guests can relax, socialize and even play pool. A second Aloft hotel will open at BWI Marshall Airport this summer.
