Dear Helen,
Thanks for coming back to visit us here at the Disney Parks Moms Panel with your ticketing question.
You can absolutely upgrade at any time to the
Park Hopper tickets, but even if you upgrade on the very last day of your visit, you will have to pay the difference for all of the days that you are there, so you will get more for your money if you start Park Hopping at the beginning of your trip and use it throughout your stay.
At this time, Walt Disney World Resort is shipping out the upgraded
MagicBands, yes! They are softer and smoother than the previous ones, and I find the new ones extremely comfortable.
Moms Panel tip - Have you heard about the new
Express Transportation option to get from Park to Park and only have to go through security once? It's a terrific new option!
Have a magical trip!!
