Strasbourg is a BIG city. It is used to absorbing both Parliamentary and Council of Europe delegates and has a large and adequate congress centre.

You will need to book your accommodation well in advance ... many delegates stay in the Holiday Inn which is not far from the European Institutions, but I am sure you will have no problems touring the centre ... after all the delegates should be at work and the docs at their conference! June is a busy month for tourism - the schools finish at the end of it and if Pentecost falls in June there are also plenty of long weekend visitors.

Book your accommodation now and rest easy. Plenty of space and loads to see and do.
