We went to Crete last year and were reluctant to keep buying bottled water, especially as we were not going to be near any shops to buy it easily and cheaply. Therefore, we investigated and discovered the ‘Water-to-Go’ website, and purchased a 50cl bottle each. It was so useful to be able to fill these up wherever we went, and even in cafes we just poured ordinary water into them ready for our walks. The real advantage came when we got delayed 24 hours at the airport and slept most of the night on the floor. Due to the heat and amount of passengers trapped in the departure lounge, they ran out of bottled water, so we were very fortunate to be able to fill up ours without worrying. We would highly recommend this product, and are preparing for a trip to Poland, when we shall be relying on our trusty bottles.
