[I]Minnie Mouse Princess Hat - It’s a princess hat (cone shape) with Minnie Mouse ears (adult size)[/I]
Any of the shops that sell souveniers should have that.
[I]Frozen Lemonade - Icee’s would be okay too, anything but iced coffee[/I]
That, I’m not sure…I’m not a frozen lemonade drinker.
[I]Ariel the Little Mermaid or Tinkerbell Hat - Floppy hat or beach hat (adult size)[/I]
This I’m not sure of but I’d check the souvenier shops. For example, the Emporium on Main Street, Star Traders in Tomorrowland, World of Disney in Downtown Disney, among many others. The Mad Hatter may also have some unique hats (there’s two - one on Main Street and one in Fantasyland).
[I]Lastly, a question on Sipper Bottles/Souvenir cups…do they allow you to refill ones from previous years? (We have the Sorceror Mickey Mouse one) How much do they charge for refills on current Sipper Bottles/Souvenir cups that you purchase same day in the park? And do you need to show your receipt for a refill?[/I]
I’m not sure but I’d think probably not. I think you can only get refills if you are eating at that certain place - I don’t think you can just walk in and refill your cup if you aren’t. At least I haven’t tried it.
