Reservations for four travelling together south of Barcelona / Madrid, only ever two available? Hi all,I have adventured without flying with my family for many years but this is my first time planning a trip using an Interrail pass. We’re planning a trip to Morocco next summer. If I can combine outward / inward train travel in the UK with the Eurostar it should come out as more economical then buying advanced tickets, but only if I can work out the reservations in Southern Spain!And this is where I am coming unstuck...I want to travel Barcelona - Málaga outwards, then either return the same way or go Málaga - Madrid - Avignon in July / August next year (yes, I really like advanced planning!!). I am using Rail Europe to check reservation prices and to get an idea of likely availabilty of reservations. Trouble is, if I request three or four reservations at once there are none available no matter how far in advance I ask to book. But if I ask for two, reservations are possible on many trains with only a week or two notice. Are there really only two pass holder reservations available
