We hear a lot of Disney music. On youtube there are very good lists with theme songs, film songs, hours to last, we just switch it on.
My daughter has many songs saved on her phone, she comes back from school and begins to dance on them without rest.
We make film marathons. We visited a Disney music concert last month - it was with orchestra, live singers, big video screen and all our the favorite songs. We use all our staff we bought from DLP (glasses, tea cups, calendars and so on) every day they in front of our eyes.
We make video evenings, photo evenings, playing all this on the big TV screen.
We make mickey mouse gingerbread cookies for Christmas (and not only) , I have a special cutting form.
We have many clothes, Tshirts, bags with Disney heros.
I like the idea with the pizza, Mrsya!
