My first cruise left out of San Juan and returned there. One of the sister ships had an engine room (I think) approx a month before we were to go on it. We were switched to go on the sister ship which caught fire on my 1st cruise. The ports were wonderful. The fire part wasn't. Thankfully, 'they' get the engine running and had no problems for the remainder of the cruise. Shortly thereafter, Cunard operated only 'Queen' ships and no cruise ships. Does anyone know the names of the two sister ships? Thank you.
