Last Wednesday, was in Royal Courtyard to get autograph with Belle who was outside Royal Hall. There as a line for the bakery (Maurice's Treats) there that reached to Main Street. I ask why and was told they have the belle rose tumblers. So while I waited with my granddaughter for Belle, my daughter jumped in the drink line.
20 mins later, I was done with Belle, Tangled was starting in the theater, and daughter was half-way through the line, so I took her place so she could see the show.
14 per, limit 2 per customer there. No AP discount, but discount is available at the tavern.
Technically the rose doesn't light up. The light is in the lid of the cup and shines down onto the rose. I don't see a way to replace the battery when it dies. The light flashes, settings for 4 flash rate, fast to slow.
Why so popular? Wife said get her a cup. I got her a cup.... not my place to ask why.
