Yes but please be fully aware you do need travel insurance too - the EHIC card only covers for small things like medication or minor treatment, if it was needed for an accident or travelling back to the UK, it would not cover this. We were pleased we had travel insurance when we had our travel document bag stolen at the airport there with passports and flight tickets and pesetas (at the time) Its a lovely island and normally not much crime (we have been several times) but please tell her to be extra careful with her bags, my husband just put his travel document bag down on the counter to sign car hire agreement at a kiosk inside the airport and next minute the bag had gone ........ turned up the next day, been found in a rubbish bin, without the money, but thankfully tickets and passports intact. Tell her to have a lovely holiday and enjoy the beaches!
