The paper provides empirical evidence on technological activity in the Spanish service sector, in particular for the tourist accommodation in the Balearics. The study wants to fulfil the lack of analyses in the field of tourism. Commonly, the study of innovation activity has been carried out from a manufacture perspective, for that reason the paper discusses the precise definition of innovation in accommodation services. The data refer to a large representative sample of hotels in Balearic Islands (Spain), providing a homogeneous set of information. The results show as higher-categories hotels are more innovative than lower-categories hotels; an aggregated measure of technological innovation presents a rate over the average for hotels that belong to a chain, and that for hotels under management contract. Half of innovative companies adjust the human capital skills and abilities. The hotel industry is a supplier-driven sector that innovates introducing R&D embodied technology rather than undertaking internal R&D activities
