Players started trickling in last week I think, guess some were early? We left CSR on Friday morning, but up until that point, we saw a sign for players to check in to get their magic band and one "welcome" table in the GDT lobby, very minimal.
We did see a large group of people (appeared to be management) walking around the resort last Tuesday night and distinctly heard the phrase "second bubble" mentioned. No walls as of Thursday afternoon that we saw. It seems players will be kept to the Casitas section.
Pretty sure Ranchos was still closed. Disney guests were at Cabanas which was getting busier and less "busy" over at Casitas when we were walking around last week.
