We're currently staying at "POP" and bought the refillable mugs....7 of them no less and from what I can see if you have ANY mug its not an issue.Ive been using a stainless lined one I bought in the gift shop for $11.95 and I see a lot of guest using anything for mugs even some of the older resort specific mugs.Thus far no ones said a word to me or anyone else that Ive wittnessed about what they have for a mug.This leads me into another off topic but Ive noticed some drastic changes in employee attitudes and the resorts themselevs even. Now its been 9 years since either of us has been back to Disney but ,though the staff seems friendly and courteous they lack some of the enthusiasm Disney has been noted for.Resort arent quite as pristine either, we ate at the "Grand Floridians 1900 Park Fare" our first night and we were looking forward to seeing the resort and to tell you the truth I was less than impressed with both the resort and the dinning experience.The resort looked to be in need of a facelift and as far as the restaurant goes I wouldnt be in a hurry to go back.We had 5;15 pm seatings and our table was sticky not to mention less than stable.Our local Pizza Delight would make a better presentation.Service was just OK but perhaps thats what you get when your held hostage to "gratuity included".My coffee came late and was never refilled ,when returning from the buffet our first plates were still at the table and some were never cleared until the very end of the meal.Thankfully we've had better meals since then, The highlight being "le Cellier" tonight.The whole experience was excellent but the pavillion was almost empty save for the "Trading Post" and most of it was given over to selling hockey Jerseys and stuffed beavers. Unfortunatley The Only Diney "magic" im feeling from this trip to WDW is our hard earned cash magically disappearing.I can see why theyve extended the 4/3 deal ,Maybe our expectations were set to high.Id certainly be interested to know what some one else has to say about this.Actually this may even be a topic for another thread.
