In Munich, in this church, i actually do not know and not sure what time is the best time to be there to get a seat. But in my experience still in nearby Kaufbeuren, we were able to get a seat on a midnight mass 30 minutes before the mass started. but it is different in every city or towns. in Munich i have not experienced there.

Don't know the answer to this. St. Peter is a good idea if you had a good preparation like a lunch or breakfast. I personally did not like the very narrow balcony, It is quite a challenge to pass between two people. But the view is rewarding. I suggest to do it however on a sunny day not like we did in the winter. Hope this helps.

No, to mi knowledge. Perhaps for bell tower that was/is under reconstruction. Church itself, no :)

Thank you for your question. It has been a long time on, seems now to be removed. We will receive a visit from Boston this Summer so this is a place we aim to visit again.

ciao, noi ci siati a fine ottobre 2014, e le visite ai campanili erano sospese per lavori in corso. Ora non so dirti se li hanno terminati e sia possibile salire sul campanile. Comunque ci sono altre chiese che offrono la possibilità di salire sul campanile, come ad esempio la Peterskirche (che è anche la più antica della città) e da cui si ha una vista spettacolare sul centro cittadino, attenzione però, ti aspettano più di 300 gradini.... il costo del biglietto è di 1,50 euro a persona. Buona vacanza.
