Non è necessaria la prenotazione, non mi era nemmeno venuto in mente di fare i biglietti on-line (come invece conviene per il Cremlino).Io ne ho vista solo una, la principale, non so se il biglietto sia bivalente (direi di no), penso che le convenga andare sul sito e leggere.

no

Yes

Платно 500 рублей постоянная экспозиция по адресу Россия, Москва, Лаврушинский перелок, дом 10

Я бы скачала информацию на русском или на английском из интернета, а потом использовала бы Google переводчик

Добрый вечер! К сожалению, не смогла раньше ответить на Ваш вопрос. В здании музея имеется лифт и доступ с детской коляской, я думаю, возможен! Главное, чтобы ребенок вел себя спокойно или спал! Выставка удивительная, до 17 февраля 2019г. Удачи Вам!

Hello! I think you can do it later, at the day before visit. I believe, you will not meet big problems with tickets. There are rarely problems with the tickets, only when a new major exhibition. I looked at the website, at the end of June there will be 1 new exhibition, not very large. When I go to the Tretyakov gallery, I always buy tickets at the box office right before visiting, and usually it takes about 10 minutes. On workdays - I never heard about problems with tickets. Have a nice trip! If you have any more questions about Moscow, don't hesitate to ask me! I can't promise a quick response, but I'll try.

Sorry to take so long-been away. I would get a metro map from the Cruise Director and make your way to the Metro line terminal about eight hundred meters walk, via the Shipping terminal, from where your boat is docked. Should be straightforward from there.
