Not to be forgotten in the transportation mix are tourist-oriented companies that not only depend on the availability of transportation to and from attractions and hotels but also on the prosperity of ambulant tourism in the form of tour buses. However, a new Los Angeles city ordinance would threaten the livelihoods of those selling tour bus tickets in Hollywood. The new ordinance calls for tour operators to abstain from selling tickets on public rights-of-way. Tour operators who normally promote their services on public sidewalks opposed the measure since that would force them to lease retail space even as their revenues continue to narrow. In related news, the prospect of another future federal government shutdown, however remote, threatens to endanger the growth of business travel, according to a trade group.
