First I have to say that was an impressive multi quote!
I can confirm the rear area of Main Street Jewelers is indeed devoted to all things Pandora. There are a series of necklaces (which I switched to this trip!) ranging from 16 inches to 20 inches. There are only about a dozen park exclusive charms, the latest released in March. I wasn't really thrilled with any of those as I had my favorites already.
They did release some Mother's Day charms in DTD while I was there but those were not Disney Park exclusive. They also had Murano Glass Bead Charms that supposedly glowed at night. I (of course) got the Tinker Bell Green but I haven't noticed it glow yet.
Summer Lace has the same charms as everyone else but the display is much smaller. I wouldn't expect any resort specific charms as Disney seems to be going to a "core" philosophy: every place has the same things. While convenient, it is also sad since there isn't anything really unique anymore. DTD, all the parks and the deluxe resorts have the same selection of charms and bags. (Animal Kingdom Lodge didn't have Dooney Bags and I'm not sure about the deluxe Epcot resorts as we didn't make it there) and they were basically all the same. I found the perfect Dooney in DTD after a sweet CM looked through their back stock for it!
When she brought it out a couple of ladies offered to buy it if I didn't want it!
And yes I spent more time shopping and eating than anything else! We only managed to make 4 fast passes in 8 days.
Current plan for years end is a
Disney Cruise in late November or Early December with a GF stay on the end of the cruise.
Happy Planning!
