Well things like that have happened to me... my first trip to London, Buckingham palace was COMPLETELY covered in scaffolding and plastic.. and then in 1999 I went to Rome and the Vatican, I swear ~ was completely covered in plastic and scaffolding - looked just like buckingham palace
At the Beach Club when I was there.. the whole buiding had ugly areas of scaffolding... mostly around the pool area.. it was a eyesore but you know what?, none of these things affected my trip... I don't go just to see one thing... it is just a tiny part of it.
We were in Disney in December and it's a small world was closed off by a wall... it was a disappoiintment because that ride is a tradition.. but you don't give it a second thought there is so many other things to see and do.
Disappointing sure, but not the end of the world. (and when you compare it to problems in the world these days - it is really insignificant)
