Hi Maria,
I think you and your family will have a wonderful, new and exciting cruise experience on QM2. I will certainly be looking forward to hearing about your crossing. We can compare our journeys - QM2 vs. Regent's CROSS, in Nov.
We ventured away from RSSC last year, taking a Deilmann river cruise. We had some minor mixed emotions, having sailed exclusively with RSSC. However, we took the plunge and were happy we did so. I have no doubt your "plunge" will be equally gratifying and enjoyable!
