Hi Melissa!
I love that you're looking for a great promotion! The Free Dining Promotions are wildly popular, as you could expect, and can save you quite a bit of money! The UK offers can and do vary, so I don't know if I'd base US availability on those offers, as offer details can be quite different in the UK versus USA.
Promotions have been offered for US residents in the past during this time period, but not consistently, so keep that in mind. If Free Dining isn't offered, I'm hopeful that they'll be another option available for you, and you'll easily be able to budget that savings toward your dining expenses. Keep your eyes on the
Walt Disney World Special Offers page for the most recent offers, and do check your email, as sometimes special offers are sent directly to guests via email.
Have a magical vacation!
Amanda
