I recently read about it because I'm planning to fly to Mallorca with my girlfriend in June. The unions there are actively promoting the idea of limiting the influx of vacationers, so the tax may well be introduced. This could affect not only accommodations, but also transportation. The Gettransfer blog explains how the
Balearic Islands tourist tax could change the demand for regular taxis and buses. The blog says that if there are fewer tourists or costs increase, many people may switch to individual transfers. For this reason, I will definitely book in advance and look for services where you can see the rates and drivers. This makes it easier to control your budget and not rely solely on local taxis during the season.
