Which theme park would be the best to go to in walt disney world?

so we are planning a family vacation to Orlando and would like to go to Walt Disney World, unfortunately we wont be there too long and we are planning to go to the park for one day. We are not getting the park hopper option since we are on a limited budget so with this being the case which park would be the best option? Magic Kingdom, Epcot, Hollywood Studios or Animal Kingdom? This will be our first time there and we want to make this an unforgettable experience, please help. Thank you!
