Duck Tours Miami. Like the campy duck tours that originated in Boston and are now commonplace in several cities across the United States, duck-themed amphibious WWII vehicles make daily 90-minute tours of Miami that combine land and sea views. Comedy, quacks, and cheese are part of the mix. There are deep discounts for kids. 1661 James Ave., South Beach, Miami Beach, Florida, 33139. 305/673–2217; www.ducktourssouthbeach.com. $32.
Island Queen Cruises. Working with nine boats, experiences on the very touristy Island Queen Cruises run the gamut—sunset cruises, dance cruises, fishing cruises, speedboat rides, and their signature, tours of Millionaire's Row, Miami's waterfront homes of the rich and famous. The Island Queen, Island Lady, and Miami Lady are three double-decker, 140-passenger tour boats docked at Bayside Marketplace that set sail daily for 90-minute narrated tours of the Port of Miami and Millionaires' Row. 401 Biscayne Blvd., Downtown, Miami, Florida, 33132. 800/910–5119; www.islandqueencruises.com.

Little Havana Arts & Culture Walk.
