Our first two trips we used the Dining Plan, and I LOVED the "carefree" feeling of having meals already paid for. I thought we would miss it terribly, but chose to stay at the Swan for the savings. I was pleasantly surprised by how much we didn't miss the dining plan!
I've heard of people loading a gift card with the amount of money they'd spend on the dining plan and using that for a "do-it-yourself" dining plan - that might help. I'm actually thinking that might be a fun experiment this time around.
By the way - there is also no Magical Express service to the Swan and Dolphin so you would need to arrange your own transportation to and from the airport and no charging privileges in the parks (which we never did anyway, so didn't miss it.)
Beyond that, I didn't notice any differences between our Swan stay and our other Disney resort stays. It's a great resort in a great location, and I love having the option of savings during a holiday week!
This time we are doing a split stay - we'll be staying at Dolphin for the Thanksgiving Holiday time period, and transferring to a Disney resort after the rates go back down. Best of both worlds!
