Elien, Irene can you two fill in pieces of information I may be missing about Brussels? It should cover:
getting to the venue + getting to the evening sites for those coming directly to the Soirees
hot spots in the neighborhood
what to bring/ wear, if anything (Belgium weather, or other local quicks)
potentially your contacts too should they need to get in touch quickly
Feel free to add all this to the travel wiki. I will be emailing all come Monday. Thanks!
