How many of the attractions close the week of Easter in Prague? What might be open to see and do if the town does close up.
Easter Sunday: what's normally closed on Sundays will be closed. Easter Monday is holiday. Expect everything on holiday schedule. Attractions are usually opened. The rest of week is like every other week.
I've been there during Easter- everything is open because it seems like every was there on vacation. I've never visited any other city that experienced such a noticable flood of tourists as Prague at Easter.
