Trip to Nikko, Helppp

Hello, let me start by saying that I am on a budget (I'm broke af)

I wanted to go to Nikko this weekend (saturday only) and was thinking of buying the 3000¥ Nikko pass. Do you think that if we buy this pass I'll be able to go without any problem to Nikko?

Because some people say that sometimes the trains are so full that they won't let you in. Is it only for the express trains or also the normal ones covered by that pass (i.e. Tobu line, if I'm not wrong)??

Pls save me🥹🥹🥹

P.s.: do you have a specific route to follow if I were to buy the 3K¥ pass?
