Business Travellers or Tourists?
If you're trying to work out does your area attract more business travellers or more tourists - rather than spending a lot of time and money into researching this, the best way to do it is just by copying the research hotels have already done.
If you go to hotels. com and search your area (below I've done Peterborough) and search prices from Monday to Monday you'll get an overall price for 7 nights. Then click the '?' Icon and you'll get a breakdown of the prices per day.
As with Peterborough, you can see the prices are higher Monday to Thursday so you can work out that there is more demand for business travellers as opposed to tourists.
