Not very impressed with the Danube River Cruise, nothing much to see. As for the monastry, it looked very impressive from the outside but we could only see limited areas inside, quite disappointing. The guides were not so good both on the bus and in the monastry, we could not hear them well because they didn't try hard enough to make us hear them, they only spoke to those near them.
Thoroughly enjoyed the concert, we got very good seats - next to the aisle. One thing needs improvement though - at the waiting area where people queue up to enter the music hall, there should be someone announcing to the people which stairway to take according to the seat numbers to avoid confusion, because there were so many people waiting to get in.
