So you can gauge my opinion better, I have cruised on the Allure and Freedom as well as on Disney Fantasy prior to trying the Voyager class. Adventure is a very good experience, with Freedom and Allure being Excellent and Almost excellent respectively.
The Adventure is older and smaller, but it is without question still a beautiful and large ship. I was not disappointed with the decor and artwork. Only minor carpet wear was noted. The ship was clean.
Staff was exceptionally friendly and ready to provide service each day. Actually the staff attitude and service was probably the best of the three RCI cruises I have tried and all were wonderful.
Starting to show wear on carpet and drapes but still an excellent choice, very roomy and beautiful lighting and decor. Lots of storage for clothes. Huge beautiful bathroom. Awesome large balcony, tons of windows and jacuzzi was used every evening. Worth every penny spent.
we took a cab to the castles/forts and toured them. The free trolley in Old San Juan was very nice little sightseeing trip.
