We spent 2 nights at CSR at the beginning of November, prior to our cruise. We stayed in Casitas 3, which was partially under renovations at the time. Other than some blocked-off hallways and maintenance guys working during the day, we had no issues at all with the construction. Took us a bit the first night to figure out how to get to the opposite side of the building to get to the bus stop, but that was it. The construction of the tower building had no impact on us at all. Still one of our favorite resorts!
