The reason Sandra and her family did not meet me was because they felt it would be a good idea to check in at 2:30AM, having travelled all the way from the Algarve without a map or internet access. Yes, you read it right - 2:30AM!!!!!
Oddly, they failed to inform me of their check-in time before booking - which I though was quite disrespectful and unjustified.
And yes, they spent 5Gb of internet in one day, as has twice been confirmed by the internet provider - they lied and then had the supreme cheek to complain about the internet speed!!! Go figure. Not welcome anymore and not recommended.
