Can I Survive a 31-Hour Marvel Movie Marathon with Kids?

My boyfriend and I are huge marvel fans, and I guess AMC is doing a 31 hour run of all the marvel movies leading up to the new avengers. Which is end of April, this man really thinks we’re going to go and I will be able to sit there for 31 hours with not needing to pump or nurse. As much as I would love to go there’s no way I’m dumping my kids on someone for a day and a half just to watch movies
