My husband and I are heading to Europe next March, and the last couple of days will be spent in Prague! We have a pretty tight schedule so our Prague time is pretty short--arriving on the overnight train at about 9:30 am on a Friday and flying out on Sunday, so we have about 48 hours altogether. I'm reading more about the Easter markets and it sounds like there is more involved than just shopping; I've seen a few mentions of shows and entertainment. Is this something that might occupy us for more than a few hours? How important would it be to try to carve out some extra time in Prague to take advantage of the markets? There's not much wiggle room in our itinerary but I could make something work!
The biggest Easter holiday in Czech (and I suspect that elsewhere in Europe, too) is Easter Monday. So you are already missing on that. You allowed very little time for Prague but you certainly can spend little time at Easter Markets. Two biggest ones are at Old Town Square (Staromestske namesti) and Wenceslas Square (Vaclavske namesti) and you would be there anyway. How long time to devote to it? I cannot say, everybody's different. To get some more information and knowledge I would recommend to google Easter traditions in the Czech Republic, Easter markets in Prague and check these websites:
if you are staying anywhere near the centre of the city then you should be able to enjoy the markets in the evenings, maybe for an hour or so before you go for your evening meal or just at the end of your day sight seeing.As the markets will be in the tourist areas you will be passing through these areas on your normal sight seeing tours.
There is often live entertainment and or buskers on in Old Town Square and along Na Prikope which is the main street that goes from the Powder Tower to Wenseslas Square.
I have been to lots of stuff in Old Town Square over the years ,ie Ice Hockey world finals on the big TV screens this May, and last year in May a children's traditional dance contest that was brilliant, also various groups doing free concerts, really just depends and if you are in luck something that appeals to you may be on.
