South Florida-based B Hotels & Resorts is adding to its portfolio with two additions: a new 'value-full-service' category called b2 hotels and a third location for the parent B brand. The next hotel will open in the downtown Disney resort area in the fall of 2013. The B in Lake Buena Vista, Fla., a conversion of the 394-room Royal Plaza, will offer a family-friendly lifestyle experience. The company's first b2 hotel will debut in downtown Miami at the site of the former Continental Bayside Hotel. The 243-room property will undergo an extensive renovation and open as b2 miami downtown.
