Hello- we went earlier this year....I remember going through some type of security, but there was virtually no line, and we went through so quickly that we did not even think about it. But this is peak tourist season, so your experience might be different.

bonjour je pense que vous devez laisser votre sac à dos à l'entrée..mais nous n'avions pas de sac à dos donc je ne peux vous certifier cela à 100%.. sinon régalez-vous , l'endroit vaut le coup de visite

Hi , I'd start at the Museum first so that you can always go back after the concert if you haven't finished. Leave the restaurant to last. Have fun, harry

I am afraid it is quite a walk .. even from the closest door of the castle -that you only go down hill with no stairs- it is a good 7-10 minutes walk

Hi mbrnardic, formal dress isn't mandatory. If there is no dress code required for the invitation, let's make sure you feel really good during the concert.

I'd say go to the booth ticket again and explain your situation. But if it doesn't work, you could try to sell your ticket to other visitors in there. it works with me before. good luck

С концертом 24 доллара,без концертас12

Yes.

Да, фотографировать можно, без вспышки, я сделал более 10 фото, если интересно -пришлю!

There is a website you might like called "praguewithfamily." It gives some great ideas for fun with children. There is a free kit you can download. I think it's fine to go to the Palace with a 3-year old. There is the changing of the guard she might like. The gift shop at the Lobkowicz Palace has great items for children including introductory books on the orchestra and about art. I think I recall coloring books. Your daughter is very fortunate to have parents who give her the gift of travel. Prague is a great city for any age.
