According to this site You Are Here Disney – Starbucks Mugscan you still buy them?
Yes. Their available in each Starbucks within each park. Mk cup is only in mk, etc. Also can use the AP discount if you're an AP holder
what about Disney Springs?
When we were there last year DS had the Orlando mug not the Florida mug. We were glad to get it there instead of having to deal with it at the airport lol.When I was there , I was able to get one in every park. However, at Disney Springs, they only had the “ you are here” Florida one. Nothing specific to Disney Springs. Of corse, that can always change.
what about Disney Springs?
