Visiting Madrid in Feb and plan to fly up to afterwards Barcelona and then get bus to Andorra. Do you need to book the bus in advance and if so how do you do this? Also how likely is it for us to be able to book acomodation for three nights? I know it's height of the season so a lot of hotels are only offering 7 night packages. Not bothered where we stay as long as it's not too expensive and near to a good beginners snowboarding area. Also can we hire everything we need once there or do we at least need to buy ski suits etc. Any suggestions or tips gratefully received. First time for winter sports and andorra!
