On our second morning we decided to go to the Reini Sofia - so we caught a cab from the hotel to the location for 6 Euro.
We got there about 10:15am and there was a huge queue already. After waiting in line for about 10 minutes 1/2 of the queue walked off - we did not know why so we joined the normal queue. It took about 80 minutes to get a ticket. Quite stupid really as we could have just bought a ticket while waiting inline on the phone and then got in earlier.
So we got our ticket at about 12:10pm and we could not go into the Picasso part of the museum until 2:45 (fixed entry time). So we accepted this - I checked online and online we could have bought it right them and had entry at 2pm to Picasso. Oh well we will learn from begin stupid and not pre-booking.
The museum seemed to be quite happy with people taking photos except in the Picasso exibition.
