@larrielaine yes they will apply it to the days that fall within the promotion.
Also for fall keep in mind they normally release FD in late April or early May but then wait to release the RO discounts until much later in the summer. If you get the chance you might book FD if it fits your schedule and then later change to RO once you can compare the two.
Just to be clear, I would pay the full room price for the Saturday and then get the discounted rate for the rest of my stay Sunday-Friday without worry or too much hassle? We’re planning on staying at POP the full week after Thanksgiving. I am not holding my breath on FD for that week. It hasn’t happened in a while but the RO rates seem possible based on previous years data.
Yes that is correct as long as you call after the promo is released to have your reservation adjusted. Based on the leak about FD that’s going around it could be possible that free dining will be offered for at least part of your stay.
