Well, first, I'd like to point out some positives. I'm not so sure they're because of the DDP specifically, but I think DDP has contributed.
Tourists are returning to my state! After 9/11, no one was vacationing here. I was personally and professionally feeling the effects of this. Tourism was down after 9/11 -- then, low and behold, a dozen hurricanes slammed into FL over the course of two years! Who in their right mind wanted to bring their children, their loved ones, their family, directly into the path of a hurricane?
So in those respects, I applaud any FL business, at that time, for being able to get tourists back here, spending their money, paying sales and hotel taxes, just generally buying here again, etc. Tourism is our industry here, and it took an awful hard hit. And this affected ME when the State of Florida couldn't pay my bills for services as a court reporter because that part of the govt. was literally bankrupt. This affected ME when I started hearing the State might impose a state income tax to make up the difference it was losing from the tourist $$$. So I'm real glad tourists have made their way back -- particularly during the hurricane/slow months of the year.
I feel the same as others with regard to the negative effects for locals and FL residents with the DDP. I think most of the TS menus have gone downhill. Eating TS generally now reminds me of a meal I might get at Bennigan's or Applebee's. I'm looking at menus right now for our anniversary in September, and even DH said that they're all the same. Maybe a sauce or herb changes, but it seems like in a few years, there will be just one "main" Disney menu to pick from at all the TS. Considering these mainstreamed menus started appearing right around the same time as the DDP was introduced, I feel they're connected. Plus, it makes sense to me. When I go to Applebee's or Bennigan's and take part in their "meal deal," my options are very homogenized, i.e., salmon, cheap cut of steak or a baked chicken dish.
The packed restaurants and the having to call so far out for a ressie, yes, is a bummer in some respects, but then I go back to my "positives" of the DDP. The restaurants are packed because tourists are back. This is good for me as a resident of FL; not so good as a frequent visitor of WDW.
Along this point, the packed restaurants and declining menus have helped me decide to try other things in Orlando when I visit for work or pleasure. A few years ago, I'd never DREAM of leaving WDW and trying any of the other parks of Orlando. Not anymore. So in a way, the effects of the DDP has helped our family expand our fun on vacation by spending less time at WDW and enjoying US, IOA and SW. And it all started over our meals at WDW.
So those are the pros and cons for this Fl resident.
