Yeah, I personally would be OK. I haven't cruised that many times but I have never spent much time in the Crows Nest. For scenic sailing areas I'm always outside, even when we were in the Arctic Circle. I found the sea spray usually makes for windows that are not the best for viewing.
What I was responding to was the suggestion that this could happen during the Panama Canal transit. To me, that's just playing the What If game to get people riled up. I do agree that this was not a good idea on HALs part and hope they will not do it in the future.
