Hi Lisa!
Nice to hear from you again! What an interesting question you pose.
It's definitely
possible to split your stay between a Value and a Moderate level resort, and to take advantage of a Free Dining Promo (or comparable offer) at both locations. In order to do so however, you'd need to secure availability under the "offer code" at both locations
in advance of arrival, and meet the minimum requirements for length of stay and ticket purchase at both resorts. If your former
Special Offer isn't available at the two resorts you had in mind, you may be offered an alternative or a different but equally valuable offer. It's all based on availability.
It's a bit tricky, but it can be done. I'd recommend that you call in and speak to a Cast Member at Vacation Package Booking. Advise them of what you're hoping to achieve, and they'll review the availability, options and price difference with you. Call (407) 939-7675 and have your current reservation number handy at the time of your call. The Cast Member can work some numbers and review potential options with you.
All the best to you! I hope you're able to put together the two-resort combination of your dreams to make this your best Walt Disney World vacation yet Lisa!
