To Disneyland??

I know it’s not pregnancy related or anything..

I’ve never been to Disneyland , just my fiancé and I are paying for ourselves and it’s free with a 1 year old.

Basically we are driving down there with my family & then flying up (since he can only take off so much time for work)

We have a place to stay @ my grandmothers house

We will be able to get the discount since she lives there.

We are going to be at the Disneyland park from March 20-23rd (3 day pass)

Basically I just want to know what we “HAVE” to do there 😉 like what are your must haves for the park?? How much money should I save for food? Souvenirs? I don’t really know what’s there to be honest.. so if I can get an idea on what I should spend money on for this trip ☺️
