so South Florida is like a second home to me. I'm coming down to Miami in a few weeks for my partners bday and want to do something different so I'm looking at an Everglades Airboat tour (among other things). Alll the tours I've found only give you 30 mins or so on the airboat. Is that the standard length of time or are there one hour options? any tour companies more reputable then others? thanks for any advice. BTW, we are staying on South Beach and I don't plan on getting a car so i'm only looking for operators in Metro Miami. Thnx.
