With record tourism comes big business, but you won’t find a front desk at one of the largest lodging groups in the state - Airbnb. The home-sharing network has almost 33,000 hosts in Florida, generating millions of dollars for it and the hosts, basically property owners who rent a room, home or a condo for a few days to a visitor. The company calls it a short-term rental and insists it is not in competition with the hotel business. The traditional hotel business is growing in South Florida.
