I am in Prague until Thursday. I have just spent ten minutes standing at the tram stop on Namesti Republiky reading about Terezin on my phone instead of going somewhere warm, which tells you most of what you need to know about how I travel. My question is practical and I hope it is not tactless. The memorial is about an hour north. I would rather go with a guide than alone, partly because I do not think I will understand what I am looking at otherwise, and partly because I know there will come a point where I want to leave, and I would like that to be allowed for. For anyone who has been. How long are you actually inside the Small Fortress, and then how long in the ghetto museum? Does the guide stay with you the whole way or hand you over at the door? And in March, is there anywhere indoors to sit between the two parts. It was 2 degrees here last night. I researched the temperature very thoroughly. I did not research my own tolerance for it.
