Is it bad to have that many nodes in the Level Blueprint?

So I am doing an escape route simulation for my school as a project. So I need the time it takes from every room to get to the outside, but I also need to build in parameters for example a fire in a certain floor. So this is the logic I came up with. Problem is I need this for 134 Rooms, and that will a be ■■■■ lot of nodes, is that bad? Or can UE4 handle that?
