Hi, Mrs. DH. My family and I just returned from the Radisson on 6/9. There are renovations taking place on the Bonaire Tower and that area is fenced off. As for noise, I didn't notice it at all except when in the pool. Even then, I didn't find it to be intrusive.
I think they will be renovating well into next year...after the Bonaire Tower is completed, the Curaco Tower will be renovated and, lastly, the Aruba Tower.
What type of room did you book? It may determine your placement and, therefore, the proximity to the construction.
