If you are looking for a stress free start and end to your holiday, I would keep your money in your pocket until you arrive and use local cabs instead. I used Hoppa for a return trip in Tenerife, to and from the airport with my wife and two young children. The experience was pretty awful and costly. On arrival at the airport there was no-one in the arrivals hall to meet us as promised. I had to call Hoppa and was told I needed to meet a nemed person by a 'change booth' inside the airport. Eventually, I found someone who was completely overwhelmed with other disgruntled passengers only to be told there was no cab and that I should use a local service and claim the money back from Hoppa. Refusing to do this, and after a long delay, a cab finally arrived to take us to the hotel. Although booster seats are required by law and were paid for, none were available for us. If this wasn't bad enough, the return leg was even worse! No cab turned up and we had to order one from the hotel. The emergency number Hoppa provided for this situation did not work! Claims have been made for both trips, but it has been over a week now for the first one and there has been no feedback, so I am losing hope for an amicable resolution. I give one star only because it's not possible to select 0.
