Construction of a new $30-million Hotel Indigo in Tampa's Channelside District should begin before the end of the year. The Sembler Co. of St. Petersburg and Tampa's BayStar Hotel Group are partners in the 168-room, seven-story hotel planned at Meridian Avenue and Cumberland Street. They expect to break ground in the fourth quarter of this year and open the doors in the first quarter of 2010, said George Glover, BayStar's chief executive. Earlier this year, BayStar bought the Heritage Hotel in downtown St. Petersburg. It will reopen it in November as a Hotel Indigo after a $3-million makeover. InterContinental Hotel Group launched Hotel Indigo in 2004 as a hip, "branded boutique" line targeting mid-market business travelers.
