I spoke to DoomHmaster last night, and she was utterly enthused about Prague. They both can't wait to go back there !
She was able to see St Wenceslas' tomb but not venerate it, as you can only peep into the Chapel and not walk in. Sadly, there were no icons of him :-(
The latter half of the week was bitterly cold, but they were both well wrapped up, and seem to have done an immense amount of exploring the city.
I'm so glad they had a brilliant time :-)
