TOMS catches hotels and venues that do not think of themselves as tour operators
A hotel that sells its own rooms under normal VAT rules is outside TOMS. But if that hotel buys in third-party transfers, tours or third-party accommodation for overflow and packages them with the stay, those bought-in elements fall inside TOMS. HMRC's Notice 709/5 is explicit: TOMS applies when bought-in travel elements are resold to the traveller, even where travel is not the operator's main activity. The analysis depends on the specific supply chain, not the operator's self-description.
