There are touch-free fountains to refill water bottles and you can even use your phone to order and pay for food in outlets. Im told its probably because my screen has a crack. Thirdly, you must take a PCR kit with you or take a test in Portugal within 72 hours of your return to the UK  it has to be negative. And dont check in without checking out the latest rules. All in all, a spend of 197, but there are cheaper options and it's worth shopping around.
the touch-free fountains are supplied with nowhere.
