We are considering using the night train as a way to get to Barcelona. The cheap airlines from the UK that are normally so cheap, are so expensive given that we are wanting to fly on part of a weekend that forms a bank holiday, with 25kg luggage each (we are picking up a long haul flight in Barcelona a few days later). We have Airmiles that we can use to get the Eurostar to Paris later in the afternoon and then pick up the train to Barcelona, first class with meals, a cabin with toilet and shower for cheaper than Easyjet and also saves us a hotel room!!
Is Rail Europe the best place to book with from the UK. Also, what would you estimate the taxi cost to be from the station in Barcelona to the main tourist area, e.g. the cathedral.
