You shouldn't expect to see much of the Grand Ducal Family until early to mid-September, that's how long their summer break usually is and they don't do much during that time. Felix's wedding is in mid-September, so I guess that not much will happen before that this year. Guillaume and Stephanie, however, are apparently going to visit Weilburg at the end of August.
They do photocalls every three or four years at Berg. They used to do some at Cabasson during the 80's, 90's and early 2000's but I don't expect that to happen again until Guillaume and Stephanie have children who can run around on the beach. A few years back, there was a picture released of the family of GD Henri with GD Jean but I wouldn't get my hopes up for that to happen again.
