@pjweaver - I was thinking along the same lines. Another addition:
single woman guest (or single parent guest with child or preteen because many crossover issues)
Esp at the Mods & Values, checking out what the lighting & walk back to the room is like from the bus stop at night. What is the bus stop or loop situation like for them. If taking the Magical Express back to the airport at the end of the vacation, how easy is it to get to the pickup point? How is the room situated for their needs. What's it like to get to & from the food court, pool, laundry facilities, etc. What's it like to eat in the food court and/or onsite restaurant either solo or as a single parent or grandparent with child in tow. eg some Values work better for this guest than others (POP vs. AS Music) & equally some Mods work better than others (FQ vs. CBR). All basic questions that we usually never think of before going but wish we had known about once we get onsite.
This demographic style lens of looking at 7&7s would be fresh, new & with a couple of key focus issues could address some practical & specific questions that WDW guests have.
ps one of the original 7&7s brought me to the DIS & the Boards. Think it was the podcast review of French Quarter. The 7&7s have absolutely been the standout headliner work of the DIS. Clearly, it's a labour of love with huge work & expense involved so always very, very much appreciated by DIS'rs.
