Disney Springs will be fine and plenty busy even before then, there are a lot of bored people and shopping is entertainment.It's highly likely some of the restaurants/shops in Disney Springs sadly never re-open. A lot of restaurants close down for lesser problems than not being open for 2 months. Hopefully a lot of the restaurants at DS are "big" enough to have had the deep pockets to ride this out.
I just wonder after the initial "curiosity" is over and people come the first week to check it out, just how many people are really going to go there with all the restrictions in place and if these restaurants shops will even find it worth staying open with such reduced traffic.
