This is where I like to remind people that WDW is not just a national tourist destination but also a huge international tourist destination. People saying that they don't want to visit for the new stores there because they have those same stores at home is a logical reason, why would I go and take hours away from my Disney day to go too Zara or Francesca's...Disney saw the Downtown Disney parking lots (that's where Town Center lives now) as money making opportunities. If you go to the outlets or even the Florida Mall you will see it filled with international travelers, Disney made a choice to use parking lot space to bring those mall stores into the already existing Disney Springs to keep the tourist, and their money on property. So ADDING to the already existing Marketplace and West Side they created Town Center (old parking lots) and The Landing (Old Pleasure Island). SO I will continue my defense for DS as not just a glorified regular shopping mall.
As far as the bus loop being away from things, if you are only doing marketplace I agree it's a walk but if you want to walk around the entire DS it is pretty central, disembark the bus make a right toward Marketplace, come over to the Landing, check out West Side, walk back over to Town Center and the buses are there. You can also take the boats between Marketplace, The Landing and West Side
Obviously if shopping is not the thing for you then you will probably not enjoy DS until night time when all the diverse street performers come out. You have a capella, bluegrass, pop, latin, Spanish guitar, instrumental, acoustic guitar,living statues. Again not sure in what regular mall you would find that. Coupled with unique Disney stores like the Dress Shop, Twenty Eight and Nine, Trend D, Christmas store, Art of Disney, Marvel Superhero Headquarters...is it crowded in the evening and the weekends? yes it is but you are at Disney what do you expect?
I am not a wealthy person, actually from the new shops I've only purchased merch from Uniqlo, Francesca's and L'Occitane but we enjoy window shopping, sometimes we go into Johnny Was just to play "guess the price" of a shiirt
we always come out short
