We're leaving next month for our trip to Krakow and Budapest. I've got our days all sketched out for activities, based on what's closed, open etc. And now, when I go to purchase the Parliament tour tickets, July 2nd is just not for sale. July 1st is, July 3rd is. Nothing on the website says it's closed on Mondays but I'm worried that's the case. Does anyone who's already done this tour see something I'm missing?
