My response, per the comments and recommendations above (which I sincerely appreicate) is this.....now that we know, plan ahead before you leave. Take the necessary precautions as recommended above, i.e. hand sanitizer, etc. All we can do is be prepared as best we can. RCCL is an excellent cruiseline and, fortunately, I have not had a bad experience. However, now that I know what may possibly happen I have no intention of cancelling my upcoming cruise and am prepared to stand or sit (excuse the language) in my lavatory in my cabin for a day if I have to.
