We recently got back from a week long stay at CSR. You will be happy to know that the construction is hardly noticeable.
The following are my opinions of the place. It's a mixed bag so please feel free to disagree with me but again, these are just my opinions...
The Pro's:
The property is absolutely beautiful. One of the most beautiful resorts I've seen.
Great pool area
Reasonable price
Bus transportation was great. We didn't share buses with other resorts. The buses were always on time and rarely overcrowded. *The one exception was the bus to Epcot. This route always seemed to be very late, once taking over an hour.
The resort did not at all feel crowded.
The Con's:
The rooms were very worn and dated. The beds creaked loudly. Overall the room was just not that impressive.
The bathrooms were terrible. Very small, very dirty, and worse of all you could hear people in other rooms using their bathrooms... it got pretty disgusting...
The Pepper Market was not very good. It didn't taste good and it made us all sick.
The layout of the Casitas section is odd. I feel almost stupid for saying this but I don't think I ever really found my way around there :-X Maybe that was me and my vacation brain.
***THE BIGGEST CON by far has to be the staff. The cast members, especially in the Pepper Market, were rude and always seemed to be in a bad mood. We encountered rude employees every single day we were there. During our stay we only encountered a hand full of friendly people working. It really killed the magic for us.
I will also say the resort is very large and sprawling but we didn't find the size to be much of an issue. You will have to walk a little to get from your room to El Centro but the walk is lovely so its hard to complain.
This resort, for us, was very much a mixed bag. I really don't know if we'll ever stay here again though. The staff really put us off to the place.
***this again was just our experience with CSR. I'm sure others have had much different experiences, hopefully better.***
