Is linking an in-park purchased MagicBand to your entire park account much easier nowadays? I'm heading to WDW soon, but haven't been for two years. On that trip I bought a band in-park and had it linked to my tickets/FastPasses and credit card right there in the store. But they couldn't link it to my room door - I had to have that done at the resort. Has this changed since I was there? Is it as easy as me putting that unique number on the back of the band into my account via the app?
