Thanks for your thoughts!
We are currently trying to decide what to do. We are booked on the Fantasy during our kids' fall break next year but for roughly the same amount of money we can go back on RCCl, on the Allure while she is still sailing out of Barcelona. The cruise itself is quite a bit cheaper but of course the flights and hotels would be more expensive.
It has been several years since our last cruise on DCL and while my youngest would like to give it another go now that she will be old enough for the Edge, my older two really enjoy RCCL and the various activities they have. Plus, the enjoy the chance to eat at the speciality dining venues and my oldest loved being old enough for the "adult" pool area on our last cruise. She isn't into the clubs so having a quiet place by the pool to relax with a virgin cocktail and a book is her idea of a good time.
As i read more and more I tend to think we would be better off making the switch for fall. Then maybe spring 2021 the youngest and I can do a short cruise on DCL as a mother/daughter trip with the older two are gone on a school trip since DH isn't a huge fan of cruising or Disney.
Please, oh please, take your family to Barcelona! And let me know how your trip goes!
