LONDINIVM AVGVSTA

I've my ticket to London, from easyJet, I've also made the hostel reservation.
Once I get to the Gatwick airport, I will take the monorail and then the tube to the central area of the city. April 15th is my departure date.

London

I think I'm not going there, besides of the fact that it costs many times the usual price, I'm having strange problems charging the tickets to my credit card.

Almost London

Because the debit confirmation is pending. I've already made the reserve; the flight is from Barajas, Madrid (MAD) to Gatwick, London (LGW). I'm not giving more details because everything still needs time. This dates add a lot of complexity to the process of searching for reasonable flight prices, I think the price I've taken isn't the best either. Gatwick is ok, it has a railroad that connects the airport with the center, but the tickets are expensive for fast trains. How difficult will be to get used to pounds!, I'll miss my local currency. Anyway, I need to see were I'm going to stay in London and what I'm going to see from the city.

It gets difficult

The issue of getting tickets from Madrid to London, round ticket, mainly beacause the price range is very wide between one day and the next; its really hard to spend the triple just for choosing that day and not the previous. In second place, some websites do not accept foreign credit/debit cards. And in the last place, every hour I spend doing research a place on the plane is taken... so, time is running out.
