How might the UK tourism industry benefit from the UK triggering article 50?

The threat of article 50 so far has had an effect on students - fewer students from Europe are choosing to come to England as they fear their funding being cut halfway through their course. So they prefer not to begin at all. It is the same for people coming to work here - they'd rather not if they think they might be turned away or kicked out of the country. This has a knock on effect of less of their friends and family coming to visit - so in this way it has affected tourism. It has also made Britain look uncertain, and people are not sure if visa applications etc will be affected so they look elsewhere for a holiday.
