At no point have I ever said Disney isn't overpriced ~ I think most my postings regarding cost are all that Disney is overpriced in the area of hotels and food, even most merchandise and upsells. I've also said that value can't be placed on the food itself because Disney food is mediocre to good at best. If you are a foodie, Disney is not the place to go with food as your emphasis.
Getting value at Disney is not related to real world costs because one has chosen to go somewhere that is expensive across the board. Getting value for your meal means the whole experience; QS or TS, service level, views, decor, atmosphere, entertainment, location ... you pay more for that than the food itself.
That coke, that Mickey bar = all optional. If it's not worth that price to a guest, don't buy it. As long as people are buying it, in Disney's book it is worth it. I used to get a Mickey Bar a couple times each trip. Have not bought one since they are now sold in grocery store. It is no longer special. No longer has value to me. Food is one area where guests can completely control what they spend, no value, don't buy in.
I stand by it ~ if you don't get value, then don't buy it. We go about 6 times a year, we keep a low dining budget, we don't book anything that does not bring value with the understanding that the price charged is not related to just the food itself. We enjoy the Rose & Garden Fireworks Dining Package, it has good value to me. To others it is a waste of money. To others the MK Fireworks Dessert Party is completely worth it, to me it is a huge waste of money. We all place different values on different things. But that value is never attached specifically to the food itself. If it were specifically for the food then Disney is having the last laugh.
They are not Disney owned. Most the stories that are strict about this, about sharing etc come from the restaurants that are not owned by Disney (most of Epcot) as they operate on their own rules.
