note: a lot of the items below only come in larger quantities. I found many of ours above in person at dollarama, michaels & party city. I linked to as many as I could find, and if not I linked similar items!
I really enjoyed putting ours together (my inner child was so happy!) but it was a lot of work and not inexpensive. Mini Jetsetter, from whom I was clearly inspired, sells travel kits already assembled (here). Unless you already own many of the items (which we did) it’d be cheaper to go this route (and way easier tbh)!
