I guess it all depends on how you approach your activities. We usually hit Disney springs at the end of the night and we hit Ghirardellis , then watch the live entertainment which is NOT something i do at my local mall. Next, the simple fact that my family is together makes it different. Again I generally don't hang out at the mall with my kids in real life.i mean you do you homie i just usually consider "disney" things i cant do at the mall. than again WDW keeps getting more generic and theres enough like you to keep buying those tickets.
Lastly, my Disney experience is more "collective". It's the "sum" of many parts. It's the parks, the resorts, the restaurants and yes even the shopping that all contribute to fabulous vacations.
And hey, I'm pretty average, I like to get my "shop on" when I go on vacations. Probably more so on vacation because in real life I lean toward the frugal side so again not at the store unless I need something.
So thanks, I consider it a harbinger of good taste that so many of us enjoy it. Even if you meant it otherwise.
