I just went on the bundestag.de website to reserve a time for this Berlin sight and found no available times in October. It shows open hours only from 6:30 to 9:45 PM, rather than 8:00 to 8:00 per the RS guide. I thought I could make this reservation a week or two in advance, but the shortened hours, plus some multi-day closures for cleaning and renovations, seem to have defeated my plan.
Can anyone help me understand why the hours are so curtailed? Is it related to parliamentary business after this month's elections? Or Covid? Does anyone have an idea how else I could get up to that dome in mid-October? (Legally of course!)
