Those with a smaller companion or two will find their downtown of choice in Chattanooga, TN. The famous Tennessee Aquarium has made quite a name for itself in the maritime world and is certainly worthy of a visit. Kids love splashing in the miniriver that surrounds the building. Back on land, the city's many museums, restaurants and food options, and walking bridge provide plenty of entertainment. Transportation won't be a problem – see the city with a river cruise onboard the Southern Belle Riverboat, and crash for the night at the historic Chattanooga Choo Choo Hotel.
