The weekend kicked off yesterday, September 1, with Force Friday. Not only were new products for Star Wars: The Last Jedi released, but some stores also have giveaways with purchase and some fun extras.
Disney World is big on souvenirs. Most rides make you exit through the gift shop so you can take a look at all the fun themed items. Other souvenirs that have become popular are themed popcorn buckets and themed drink ware (steins, mugs, etc.).
